The Chain Rule says the derivative of f (g (x)) = f' (g (x))g' (x) The individual derivatives are f' (g) = cos (g) g' (x) = 2x So d dx sin (x 2) = cos (g (x)) (2x) = 2x cos (x 2) Another way of writing the Chain Rule is dy dx = dy du du dxComposite Function A composite function is a function which is made by combining two or more than two functions For example, if {eq}f(x) {/eq} and {eq}g(xOr the value of the function evaluated at 2x Giving a name f to a function for the function using independant variable x will be named as f (x), to be read, the function f of x Shown alone, f and x are not factors, but are a complete name

For example, if we apply the function f to f(x), we have ff(x) or f 2 (x) f 2 (x) = ff(x) = f(x 3) = (x 3) 3 = x 9 One thing to note when calculating composite functions is that fg(x) is unlikely to be the same as gf(x) For instance, from using f(x) and g(x) from our example above, we can calculate gf(xExplanation substitute g(x) = 4x −1 into f (x) ⇒ f (4x −1) = (4x −1)2 3(4x − 1) = 16x2 −8x 1 12x − 3 = 16x2 4x −2 ⇒ (f ∘ g)(x) = 16x2 4x −2 to evaluate (f ∘ g)(0) substitute x = 0 into (f ∘ g)(x)The functions are combined to form the new functions h(x) = f(x) g(x) and j(x) = f(x) g(x) Point (6, 2) is in the function h(x), while the point (2, 10) is in the function Simpson's rule Is the simpson's rule always more accurate than the midpoint rule and trapezoidal rule?
(c) If x = 3, what is f(x)?Knowledgebase, relied on by millions of students &Inverse Functions Inverse functions are functions that undo one another In other words, if f1 (x) is the inverse of f(x), then f(f1 (x)) = f1 (f(x)) = xWe can use this definition to solve
And ( f o g)(x) means f (g(x)) That is, you plug something in for x, then you plug that value into g, simplify, and then plug the result into f The process here is just like what we saw on the previous page, except that now we will be using formulas to find values, rather than just reading the values from lists of points Given f(x) = 2xGiven f(x) = 23x Replace x with g(x) f(g(x)) = 2–3(x1) Simplify f(g(x))= 23x3 f(g(x))=53x QED= 2x 3 x 2 2 The domain of (f g)(x) consists of all xvalues that are in the domain of both f and g In this example, f and g both have domain consisting of all real numbers, therefore (f g)(x) also has domain consisting of all real numbers The Difference of Two Functions
If the domain of a function F is the set of all real numbers and the domain of a function G is the set of all real numbers, under what circumstances do (FG)(x) and (F/G)(x) have different domains?1,034 272 #2 the letter which you use to label a function has no special meaning g (x) just identifies a function of x, in the same way as that f (x) does Using a g instead of an f only means the function has a different label assigned to it Typically this is done where you have already got an f (x), so creating another one would be confusingSecond component * derivative of the first component Step 3 Now add those two together xf' (x)f (x) to arrive at g' (x)=xf' (x)f (x) Yet another way to remember it first times the derivative of the second second times the derivative of the first
The composite functions of higher math often use h(x) and g(x), in combination,,defining which comes first, and which is second The substitution is bad enough, but using y's would make it worse In summary, feel free to immediately use y = instead of h(x), if it clarified the problemStep1 x*f' (x) ==>Therefore, let f(x) = g(x) = 2x 1 Then, f(x)g(x) = 4x 2 4x 1 = 1 Thus deg(f⋅g) = 0 which is not greater than the degrees of f and g (which each had degree 1) Since the norm function is not defined for the zero element of the ring, we consider the degree of the polynomial f(x) = 0 to also be undefined so that it follows the rules of a

Find (f g)(x) for f and g below f(x) = 3x 4 (6) g(x) = x2 1 x (7) When composing functions we always read from right to left So, rst, we will plug x into g (which is already done) and then g into f What this means, is that wherever we see an x in f we will plug in g That is, g acts as our new variable and we have f(g(x)) 12*f (x) means two multiplied by the function f f (2x) means the function at 2x;B (1/4x)^2 will widen the parabola C 4x^2 is too wide to be g(x) D (16x)^2 is too narrow to be g(x) A is the correct answer When graphed on desmos com / calculator it shows this is the correct answer I hope this helped!

Odd functions If f ( x) is an odd function, then for every x and − x in the domain of f, − f ( x) = f ( − x) Graphically, this means that the function is rotationally symmetric with respect to the origin Thus, rotations of 180 ∘ or any multiple of 180 ∘ do not affect the function's appearance Good examples of odd functionsAs an example, a classic result of Ritt shows that permutable polynomials are, up to a linear homeomorphism, either both powers of x, both iterates of the same polynomial, or both Chebychev polynomials We say f and g commute (with respect to composition) The property is called commutativitySOLUTION Find (fg) (x), (fg) (x), (f*g) (x) and (f/g) (x) for each f (x) and g (x) 2 f (x)= 8x^2 g (x)=1/x^2 I'm having trouble understanding what i have to do, please help You can put this solution on YOUR website!
