Question

Write the equation of the parabola in vertex form.     With a vertex (–4, 3), and a point (4, 131)

Answer 1

vertex form is f(x) = a(x + 4) + 3 where a is a constant

plug in the point (4,131):-

131 = a(4+4) + 3
128 = 8a
a = 16

so we have f(x) = 16(x + 4) + 3 . Thats the parabola.

Answer 2

Vertex form : y=2(x+4)^2 + 3
