h is a trigonometric function of the form h(x)=a sin(bx+c)+d. Below is the graph h(x). The function intersects its midline at (-pi,-8) and has a maximum point at (pi/4, "-1.5)." Find a formula for h(x). Give an exact expression.

The function intersects its midline at (-pi,-8) and has a maximum point at (pi/4, "-1.5). The final equation is h(x) = 4 sin(2x + π /2) + 3.

What is a function?

A function is defined as a relation between the set of inputs having exactly one output each.

The function intersects its midline at (3π/4, 3) then the midline is d= 3.

The amplitude is just the positive distance between the maximum/minimum and the midline,

so the amplitude a = 7 - 3 = 4

Also, given that period is 2π/b and the fact that the period is π from our given maximum,

we have the equation 2π/b= π where b = 2

we know that the phase shift, -c/b is - π/4 (or to the left)

since -π /4. Therefore, c = π /2.

our final equation is

h(x) = 4 sin(2x + π /2) + 3.
