One person is holding a laser pointer at a height of 3 feet whose beam is reflected on the glossy floor at a point 7 feet away from her. A wall is 4 feet away from where the beam is reflected. When the y axis is placed as the vertical line of the pointer and the x axis placed at the same height of the reflection point, the absolute value equation that represents the situation is shown below.

How high (h) in feet the did the laser beam will impact the wall placed 4 feet from the reflection point? Write the solution as h=...

f(x)=37|xâ’7|
