Question

Which equation represents the standard form of the equation y= (x + 3)² - 4?

A. y=x² + 3x-4
B. y=x2² +6x+5
C. y=x² + 6x-4
D. y=x2²+3x+5

Answer 1

The answer is B.
`y = x^2 + 6x + 5`

Explanation:

Because
`y = (x + 3)^2 - 4 = x^2 + 6x + 9 - 4 = x^2 + 6x + 5`

So the answer in this question is B.
