Question

What is the value of p in the equation y2 = -12x?

Answer 1

The given equation is

`y^2=-12x`

Recall that the general equation of the parabola is

`y^2=4px`

The given equation can be written as follows:

`y^2=4(-3)x`

Comparing this equation with general equation, we get p=-3

Hence the value of p is -3.
