Question

Below is the graph of a trigonometric function. It has a minimum point at (-2,-5.2) and an amplitude of 1.1. What is the midline equation of the function?

Y=

Answer 1

`y_(minimum) = - 5.2 \\ y_(maximum) = - 5.2 + 1.1 \\ y_(maximum) = - 4.1`

`midline = (y_(maximum) + y_(minimum) )/(2) \\ midline = ( - 5.2 - 4.1)/(2) = ( - 9.3)/(2) = - 4.65`

`midline \: \: \: \: y = - 4.65`
