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. 

2. What is the period of the equation y=3sin(x)? 

A6pi 
B1/2pi 
C2/3pi 
D1.5pi 
E 2pi 
F 4pi 

12. What is the period of the equation y=sin(4x)? 

A6pi 
B2pi 
Cpi/4 
Dpi/2 
E 3pi 
F 4pi 

3. What is the amplitude of the equation y=3sin(x) + 2? 

A1 
B2 
C3 
D4 
E 5 
F 6 

4. The point (0,0) lies on the graphs of which functions? 

Asine, tangent, and cotangent 
Bcosine and secant 
Ctangent and cotangent 
Dsine and tangent 
E sine, cosine, and tangent 
F cosine and cosecant 

5. The graph u identified on #3 is a light plot for another planet. What's the length of a day on that planet? 

Acannot be determined 
B25 hours 
C20 hours 
D15 hours 
E 10 hours
