Question

Find the midline for f(x)=sinx+1.
a. y=0
B. y=−1
C. y=1
D. y=−2

Answer 1

B Y=1

Explanation:

Answer 2

C

Explanation:

What is the greatest value that sin(x) + 1 can have? It isn't 1.

f(90) = sin(90) + 1

f(90) = 1 + 1 = 2

What is the smallest value that sin(x) + 1 can have? It still isn't one.

f(-90) = sin(-90) + 1

f(-90) = -1 + 1 = 0

So the midline is (2 + 0)/2 = 1

y = 1 is the answer.
