Question

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

Explanation:

Step1: Identify maximum and minimum

The maximum value of the graph is $y = 1$ 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 $y_{max} = 1$ and $y_{min}=-5$ into the formula: $y=\frac{1+( - 5)}{2}=\frac{1 - 5}{2}=\frac{-4}{2}=-2$.

Answer:

$y = - 2$
