Answer:
a=1
b=-4
The graph is a parabola with vertex in (2,-9), y-intercept (0,-5) and x-intercepts (+5,0) and (-1, 0)
Step-by-step explanation:
[tex]xv = \frac{ - b}{2a} [/tex]
[tex]yv = f(xv)[/tex]
y-intercept: P(0, c)
x-intercepts: find x1 and x2 with the quadratic formula, then P1(x1, 0) and P2(x2, 0)
