Question

Choose the letter of the equation for

the graph.
KIN
2
a. y =
sin x + 2
b. y = cos x + 2
c. y = cos(x - π)
d. y =
sin(x - π)
e. y = sin(x + π/2)
Enter

Answer 1

a

Explanation:

The midline is at y=2.

Eliminate c, d, e

Also, since there is no horizontal shift amongst the remaining options, we know that since y=2 when x=0, this means it must be a sine curve.

This means the answer is a.
