Question

What is the amplitude of the function?

Answer 1

Answer:

2

Step-by-step explanation:

Take the absolute value of the lowest y value.

So

$| - 1| = 1$

Take the absolute value of highest y value.

$|3| = 3$

Add those two together and divide by two.

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

So the amplitude is 2
