Question

Describe the transformation.y = (x + 7)2 - 4

Answer 1

The parent function of the quadratic function is

`y=x^2`

∵ x is added by 7

∴ The graph of the function is translated 7 units to the left

∴ The image of the function will be

`y=(x+7)^2`

∵ The function is added by -4

∴ The graph of the function translated 4 units down

∴ The image of the function will be

`y=(x+7)^2-4`

The transformation is

Shift 7 units left and shift down 4

The answer is D
