Question

Anyone able to answer this for me rq rq? :( spending my last chunk of points of this

Answer 1

Part A: y = -5 (x)(x-4)

Part B: 8.75m

Explanation:

Part A:

y = a (x-4)(x-5)

y = a(x-0)(x-4)

20 = a(2-0)(2-4)

20 = a (2)(-2)

20/-4 = -4a/-4

a = -5

∴ y = -5 (x)(x-4)

Part B:

y = -5(0.5)(0.5-4)

= 8.75m
