Use the graph below to answer the question that follows: What trigonometric function represents the graph?

f(x)=-2cos(x- pi/2)
f(x)=-2sin(x- pi/2)
f(x)=2cos(x- pi/2)
f(x)=2sin(x- pi/2)

the formula of a slope:

from a table we have

substitute:

the slope of f(x) is -1.

the graph of funcfion g(x) is a horizontal line. the slope of a horizontal line is equal 0. therefore the slope of g(x) is 0.

-1 < 0

describing distributions is one of the key skills you’ll need to earn a high score on the ap statistics exam. if you need proof of this, just flip through some past exam questions, which can be found at the collegeboard website. you’ll notice that the first free response question is almost always a question requiring you to look at a graph and describe it.
