Answer:

3rd option

Explanation:

The equation of a parabola in vertex form is

f(x) = a(x - h)² + k

where (h, k) are the coordinates of the vertex and a is a multiplier

Here (h, k ) = (- 1, - 25 ) , then

f(x) = (x - (- 1) )² - 25 , that is

= (x + 1)² - 25 ← expand using FOIL

= x² + 2x + 1 - 25

= x² + 2x - 24
