Determine The equation of the midline of the following graph

y = -2

Step-by-step explanation:

In the figure, we can see a periodic function which maximum value is -1 and minimum value is -3.

The equation of the midline of a periodic function is the average of the maximum and minimum. For this case, this average is [-1 + (-3)]/2 = -2, then the equation is y = -2

answer: on graphs, the open and closed circles, or vertical asymptotes drawn as dashed lines us identify discontinuities.

as before, graphs and tables allow us to estimate at best.

when working with formulas, getting zero in the denominator indicates a point of discontinuity.

when working with piecewise-defined functions, check for discontinuities at the transition points where one piece ends and the next begins.
