SOLUTION: y = -x^2 + 7x - 2 I need to graph this quadratic function. I know I will need to use -b/2a and find y, but I am quite confused on how to solve this problem.

will give you the vertex and the axis of symmetry.

You can then plot points equidistant from the vertex (they have the same y value).
x=3 and x=4 would give the same y, y=-9+21-2=10
x=2 and x=5 would give the same y, y=-4+14-2=8
x=1 and x=6 would give the same y, y=-1+7-2=4
x=0 and x=7 would give the same y, y=0+0-2=-2
