Question

Use complete sentences to explain how you would use graphing technology to find the solutions of 0 = −x2 + 2.5x + 1. What do the solutions of 0 = −x2 + 2.5x + 1 represent on the graph of the equation?

Answer 1

I would plot\[y=-x ^{2}+2.5x+1\] And,y=0
The intersecting points represent the roots of the equation.

Answer 2

i dont know, can you answer it for me?
