Question

The zeros of a parabola are-5 and -3. The point (0, 60) is on the graph as represented by the equation.

Answer 1

Answer:

a=4

Step-by-step explanation:

Given that The zeros of a parabola are-5 and -3.

Hence parabola would be of the form

y =a(x+5)(x+3)

To find a:

A point (0,60) on the parabola is given

Substitute this point in the equation

$60=a(0+5)(0+3)\\15a=60\\a=4$

Hence answer is

a=4
