Question

For the parabola y = (x+14)^2 -4, The value of the y coordinate of the vertex is?

Answer 1

y - coordinate = - 4

Explanation:

The equation of a parabola in vertex form is

y = a(x - h)² + k

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

y = (x + 14)² - 4 ← is in vertex form

with vertex = (- 14, - 4 )

The y- coordinate of the vertex = - 4

Answer 2

-4

Explanation:

y = (x+14)^2 -4

The equation is in vertex form

y = a(x-h)^2 + k where (h,k) is the vertex

The y coordinate of the vertex is k = -4
