Question

Use the function below:

What are the amplitude and midline? (5 points)

Amplitude: 4; midline: y = 1
Amplitude: 5; midline: y = 1
Amplitude: 5; midline: y = 0
Amplitude: 4; midline: y = 0

Answer 1

A

Amplitude: 4; midline: y = 1

Step-by-step explanation:

Amplitude = (min-max/2)

= 8/2

= 4

midline is just the middle which = 1

Answer 2

The correct option is Amplitude: 5; midline: y = 1.

Step-by-step explanation:
Amplitude is the greatest distance/position from the axis. Since the top of the curve, strikes the y-axis at y= 5. Thus, amplitude is 5.
Midline is the point where the centre line (symmetry line passes). Clearly, in this curve the symmetry line is y= 1. So, midline is 1
