Answer:
see explanation
Step-by-step explanation:
The amplitude is the value from the x- axis to the maximum, thus
amplitude = 2
the midline is the line midway between the minimum and the maximum
Assuming the graph is symmetrical about the x- axis
Then the max is 2 and the min is - 2
y = [tex]\frac{-2+2}{2}[/tex] = [tex]\frac{0}{2}[/tex] = 0
Thus the midline is y = 0
