The equation of the parabola shown in the 12b is y = x² - 4 if the vertex of the parabola is (0, -4).

<h3>What is a parabola?</h3>

It is defined as the graph of a quadratic function that has something bowl-shaped.

(x - h)² = 4a(y - k)

(h, k) is the vertex of the parabola:

a = √[(c-h)² + (d-k²]

(c, d) is the focus of the parabola:

It is given that:

The graph of a parabola is shown in the 12b question:

As we know, the standard form of the parabola is:

y = a(x - h)² + k

(h, k) is the vertex of the parabola:

From the graph: h = 0, k = -4

y = ax² - 4

Plug (2, 0) in the above equation:

0 = 4a - 4

a = 1

y = x² - 4

Thus, the equation of the parabola shown in the 12b is y = x² - 4 if the vertex of the parabola is (0, -4).
