The graph of y = f(x) is shown below. ← 6 y 4 2 y= f(x) 6 -4 -2 2 4 Sketch graph of the function y = √f(x) given the graph of the function.

How do you find the domain for the composition of two functions, fg ?

For the fallowing exercises, find the x- and y-intercepts of the graphs of each function. 11. f(x)=2x+1+6

How do the graphs of the functions f(x)=x2 and f(x)=x21 differ? We graphed them at the start of this section. What is the difference between their graphs? How are their graphs the same?
