The zeros of a parabola are 6 and −5. if (-1, 3) is a point on the graph, which equation can be solved to find the value of a in the equation of the parabola? 3 = a(−1 + 6)(−1 − 5) 3 = a(−1 − 6)(−1 + 5) −1 = a(3 + 6)(3 − 5) −1 = a(3 − 6)(3 + 5)

ANSWER

EXPLANATION

The equation of a parabola in factored form is

where 'a' is the leading coefficient and 'm' and 'n' are the zeros.

From the question, the zeros of the parabola are 6 and −5.

This implies that,

We plug in these zeros to get:

If (-1, 3) is a point on the graph of this parabola,then it must satisfy its equation.

We substitute x=-1 and y=3 to obtain:

The first choice is correct.

hi,

i'm 75% sure the answer is 1,1 to both lines.

have a great day
