** what is the amplitude of the function graphed?

So amplitude is the length from the highest (or lowest) point from the mid-line of the function

In this case the mid-line is y = 1

The highest point, which has a y of 3 is 2 units away from the mid-line. This means that the amplitude is 2!

Hope this helped!

b. y = 4x - 2

step-by-step explanation:

to find a parallel equation to an equation, make sure both equations have the same slope but different y-intercepts.

y = 4x + 1

4 = slope

1 = y-intercept

y = 4x - 2

4 = slope

-2 = y-intercept

they both have the same slope but different y-intercepts, so, b. is the correct answer.

and to check your work, you can graph both equations. : )
