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:

The value of 'a' is 4

Step-by-step explanation:

To find 'a', we just have to simplify and make 'a' the subject of

$60 = a(0 + 5)(0 + 3)$

This gives us:

$60 = a(3)(5)$

This implies that:

$60 = 15a$

We divide both sides by 15 to get:

$a = \frac{60}{15}$

$a = 4$
