Answer:
a. y = -7cos(x) +7
Step-by-step explanation:
The middle level of the gum is 7 inches above the ground, and it oscillates 7 inches either side of that. Thus the offset of the cosine function (average height) is 7 and the multiplier (amplitude of oscillation) is also 7. The -7 on the cosine multiplier means the height of the gum is zero at x=0.
It’s A, as you can tell from my picture
