determine the equation of the midline of the following graph. answer attempt 1 out of 2

Explanation:

Step1: Identify maximum and minimum values

The maximum value of the graph is $y = - 3$ and the minimum value is $y=-5$.

Step2: Use mid - line formula

The formula for the mid - line of a periodic function is $y=\frac{y_{max}+y_{min}}{2}$. Substitute $y_{max}=-3$ and $y_{min}=-5$ into the formula: $y=\frac{-3+( - 5)}{2}=\frac{-3 - 5}{2}=\frac{-8}{2}=-4$.

Answer:

$y = - 4$
