Question

What is the standard form of the equation y = (x + 2)^2 -3

y = x^2 + 4x - 3
y = x^2 + 4x + 7
y = x^2 + 4x + 1
y = x^2 + 4x - 3

Answer 1

C. y = x² + 4x + 1

Explanation:

y = (x + 2)² - 3

y = x² + 4x + 4 - 3

y = x² + 4x + 1

Answer 2

y=x^2+4x+7

Explanation:

y=(x+2)(x+2)-3

y=x^2+2x+2x+4-3

y=x^2+4x+7
