Question

Determine the points of intersection of the given

functions.
y=-x2 + 3x + 20
y = -2x + 15
Describe the features of the graphing calculator you
would choose and why.

Answer 1

Sample Response:

When graphing the functions in the standard viewing window, the points of intersection are not visible. So, grabbing and sliding the window down or zooming out twice will get the points of intersection in view. Another option is to change the window settings. Once the intersection points are in the window, hovering over them will show the coordinates.
