Question

Which equation has a graph that is a parabola with a vertex at (–2, 0)?

Answer 1

Comparing to the standard equation, the parabola with a vertex at (-2,0) is given by:

y = (x + 2)²

What is the equation of a parabola given it’s vertex?

The equation of a quadratic function, of vertex (h,k), is given by:

y = a(x - h)² + k

In which a is the leading coefficient.

In this problem, we have that h = -2 and k = 0, and all the options have leading coefficient a = 1, hence the equation is:

y = (x + 2)²
