As Freda gazes at the edge of the Grand Canyon, she decides to try to determine the height of the wall opposite her. Using an app on her phone, she determines that the top of the wall is at a 38° angle above her, while the bottom is at a 46° angle
below her, as shown in the diagram at right. If the base of the wall is 253 feet from the point on the ground directly below
Freda, determine the height of the wall opposite her.

we have

using a graphing tool

see the attached figure

this is a quadratic equation (vertical parabola) open up

the vertex is a > vertex

the domain of the function is all real > interval (-∞,∞)

the range of the function is the > [-6.125,∞)

the function has two x->   and

the function is increasing over the > (0.25,∞)

the function is decreasing over the > (-∞,0.25)
