60 seconds equals one minute.
The equation represents the parabola shown on the graph is x^2 = - 8y . Option D
<h3>How to determine the equation</h3>
We were given the following parameters;
- Vertex ( 0, 0 )
- Focus ( -2, 0)
- Directrix , at x = 2
The standard for a parabola is given as;
y² = 4ax
It can also be written as;
x² = 4ay
Given the focus as ( -2, 0), we have the value of 'a' to be -2
Now, let's substitute the value into the standard equation of a parabola
x^2 = 4ay
x^2= 4 × -2 × y
Multiply through
x^2 = - 8y
The equation of the parabola is x^2 = - 8y
Thus, the equation represents the parabola shown on the graph is x^2 = - 8y . Option D
