Use the pythagorean theorem (A squared + b squared = c squared
The roller coaster could be represented by the function for Choice D.
If you were to graph this function, you would find that the zeros (x-intercepts) of the function are at the points of -2 and 1. Those are the needed points in the problem.
Since this is a parabola that opens upward, the parabola must be below the axis (or support bar) between those values.
Ok got it. If you have any questions just ask in the chat below :)
