Section 4.8 1. Match each of the graphs A-F with one of the functions (a) (f) in the following table. (In (f) try to find a suitable function which has the remaining graph.) (a) y = 5x2 - x - has graph (b) y = 2v2 - x has graph (c) y = - ;x2 + x + has graph (d) y = (=) - 2 has graph (e) y = 2Vx - 2 has graph (f) y = has graph A B C D E F Explain your answers. Note three important facts which may help you with (f): 1) If y = f(x) then y = -f(x) flips an arbitrary function about the x-axis. 2) If y = f(x) then y = f(-x) flips an arbitrary function about the y-axis. 3) If y= f(x) then x = f(y) (exchaging x and y) flips an arbitrary function about the line y=x
