Find the equation of the midline of the function y = 2 sin(1∕4x) – 3. A) y = –3
B) y = 3
C) y = 2
D) y = 1∕4

Explanation:

The general sine equation is

y = A*sin(B(x-C)) + D

where the D variable directly determines the midline. In this case, D = -3, so that corresponds to a midline of y = -3

The sine curve oscillates going up and down, passing through this middle horizontal line infinitely many times. See the graph below.
