Express x²+4x-7 in the form (x+a)²-b where a and be are integers

(x + 2)^2 - 11.

Step-by-step explanation:

f(x) = x^2 + 4x - 7

So  x^2 + 4x = (x + 2)^2 - 4 so we have:

f(x) = (x + 2)^2 - 4 - 7

f(x) = (x + 2)^2 - 11.

your answer is the last one

step-by-step explanation:

divide the length of a'c' by the length of ac to get a scale factor of two

& then reflect vertically (over the y-axis)

so your answer is dilation by a scale factor of 2 followed by reflection over the y-axis
