What is a function that matches the description?
A Sinusoidal Function has a y-intercept at 4, midline y=4, and maximum value of 8 and completes 4 cycles of the interval [0,2π]

Option 1

Step-by-step explanation:

f(x) = Asin(Bx) + C

C = 4

B = 4

A = 8-4 = 4

f(x) = 4sin(4x) + 4

step-by-step explanation:

look at the picture.

y-intercept for the function on a picture is 4 → point (0, 4).

y-intercept for the function

is for x = 0. substitute:

y-intercept is 8 → point (0, 8).
