Find the domain of inner function g(x). Find f(g(x)) algebraically and find its domain. Find theintersectionof both domains. How to Find the Range of F of G of x? The range of f(g(x)) doesn't depend on either the range of f or the range of g. So the range of f(g(x)...

Example: finding the quotient of two functions 1.find (f/g)(x) and state the restrictions on the domain if f(x) = (x+4)(x-7) and g(x) = 2(x +4) Step 1: Divide one function by the other to get the quotient of the two functions. (f/g)(x) = f(x)/g(x) By dividi...

In the case of sine functions, the parent function is sin(x), and its period is 2 pi. How do you find the period of a sine wave? To find the period of a sine wave with equation f(x) = sin(Ax), use the formula Period = 2pi/|A|. If |A| = 1, then the period of the ...
What are the steps for finding asymptotes of rational functions?Given a rational function (that is, a polynomial fraction) to graph, follow these steps:Set the denominator equal to zero, and solve. The resulting values (if any) tell you where the vertical asymptotes are. Check the degrees ...
Accelerate’s vDSP module provides functions to perform 1D fast Fourier transforms (FFTs) on vectors of data, such as audio signals. The example below shows an input signal (left) and its frequency domain representation (right) after transforming the signal with a forward FFT.You...
Finding the x- and y-intercepts may be done either graphically or algebraically. Functions and equations may either be linear or nonlinear. Linear functions are those drawn with a straight line as seen in the illustration below: Graph of y = 2x - 6 with x- and y-intercepts...
