Question

Please help ASAP!

Use the graph below to answer the question that follows: What are the amplitude, period, and midline of the function?

Answer 1

Amplitude:

we can see that

maximum value is 3

minimum value is -1

so,

$A=\frac{max-min}{2}$

$A=\frac{3+1}{2}$

$A=2$

Period:

It is time completed after which value repeats itself

so, we get

$T=\pi -0$

$T=\pi$

so,

option-D............Answer
