1. Which direction would y=cos(x-2) shift?

A 2 to the right

B 2 to the left

C 2 up

D 2 down

E It wouldn't shift, the period would be shorter.

F It wouldn't shift, the amplitude would be 2 to -2.

10. Why does the graph of the secant function have breaks in it?

ABecause the secant function is undefined at pi.

BBecause the secant function is undefined at pi and -pi.

CBecause the secant function is undefined at 0.

DBecause the secant function is undefined at 90° and -90°

E Because the secant function has to reach infinity, which doesn't really exist.

F Because the secant function has to have a break in it to be a function.
