Question

Y=(x-4)^2+3
Write in standard form (show all steps)

Answer 1

y = x² - 8x + 19

Explanation:

The equation of a parabola in standard form is

y = ax² + bx + c ( a ≠ 0 )

Given

y = (x - 4)² + 3 ← expand parenthesis using FOIL

= x² - 8x + 16 + 3

= x² - 8x + 19 ← in standard form

Answer 2

I’m not gonna show my steps but the answer is Y= x^2-8x+19
