PLS HELP (:

Which answer describes the transformation of f(x)=x^2−1 to g(x)=(x+4)^2−1 ?

a vertical translation 4 units down
a horizontal translation 4 units to the left
a vertical stretch by a factor of 4
a horizontal translation 4 units to the right

Answer 1

B) a horizontal translation 4 units to the left

quadratic equations in vertex form are:
y = a (x-h)^2 + k, where a is the "stretch factor",
the vertex lies at the point: (h, k)
So since the only change is by the h increasing by 4, that translates to a left shift of 4 units.

Answer 2

The answer is B
