c. Compare the graphs of y = f(x) and y = -f(x).

d. Compare the graphs of y = f(x) and y = f(-x).

e. Explain the effect of c on the graph of y = f(x) for the function y = cf(x).

f. Explain the effect of c on the graph of y = f(x) for the function y = f(cx).


plz help...im so confused

Answer 1

so...how much do you know? haha
