Question

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

Explanation:

Step1: Recall the midline definition

The midline of a trigonometric graph is the horizontal line that lies exactly between the maximum and minimum values of the function.

Step2: Identify maximum and minimum values

From the graph, assume the maximum value \(M\) and minimum value \(m\). The midline \(y = \frac{M + m}{2}\). Observing the graph, if we consider the vertical axis (x - axis here is vertical, y - axis is horizontal). The maximum value (upper part of the wave) and minimum value (lower part of the wave) are symmetric about \(y = 0\).

Answer:

\(y = 0\)
