Question

How do you write `y= -0.015x^2+1.501x-17.157` into vertex form?

Answer 1

Vertex form of y.

Explanation:

x of vertex: `x = (-b/2a) = -1.501/-0.03= 50`

y of vertex: y = f(50) = - 0.015(2500) + 1.501(50) - 17.157

= - 37.5 + 75.01 - 17.157 = 20.39

Vertex form: `y = - 0.015(x -50)^2 - 20.39`
