Use a graphing calculator to sketch the graph of the quadratic equation, and then give the coordinates for the x-
intercepts (if they exist).
y= -x2 + 15x - 56
a. (-7, 0); (-8,0)
c. (-7, 0); (8,0)
b. (7,0); (-8, 0)
d. (7,0); (8,0)

What are the solutions of the system? solve by graphing. y = x^2 + 3x + 2 y = 2x + 2
