Question

Re-write the quadratic function below in Standard Form y= 3(x - 1)^2 - 8

Answer 1

Answer:

y = 4x ^ 2 - 8x + 6

Explanation:

y = 4 * (x - 1) ^ 2 + 5 This is Vertex form.

Expand & simplify

y = 4(x - 1) * (x - 1) + 5

y = 4(x ^ 2 - 2x + 1) + 5

y = 4x ^ 2 - 8x + 4 + 5

y = 4x ^ 2 - 8x + 9 This is Standard form.
