Question

Plz help me with this

Answer 1

It's the second option.

y = -2 sin x + 2

Tell me if I'm wrong :)

It looks spiker because my graph is more spread out with the intervals.

Answer 2

Answer: b) y = -2 sin x + 2

Explanation:

The standard equation for a sine graph is: y = A sin (Bx - C) + D

`\text{Amplitude (A) = }(max-min)/(2)=(4-0)/(2)=(4)/(2)=2\\\\\\\text{Vertical Shift (D) = max - amplitude = }4 - 2 = 2`

A sine graph starts at the origin and tends upward. The given graph stars at the origin and tends downward so it is a reflection → - sin x

⇒ y = -2 sin x + 2
