Answer:

y= - 8

Step-by-step explanation:

If your ptoblem was:  Y = X (2) - 4

The it would be:

Y = - 2 (2) - 4

Y = - 4 - 4

Y = -8

So, Y = - 8, is your answer

If the value of the x is negative 2. Then the value of the y will be 0.

What is the equation of the parabola?

It's the locus of a moving point that keeps the same distance between a stationary point and a specified line. The focus is a non-movable point, while the directrix is a non-movable line.

Let the point (h, k) is the vertex of the parabola and a is the leading coefficient.

Then the equation of the parabola will be given as,

y = a(x - h)² + k

The equation of the parabola is given below.

y = x² - 4

Then the vertex of the parabola is at (0, -4).

If the value of the x is negative 2, then the value of the y will be

y = (-2)² - 4

y = 4 - 4

y = 0

The value of the variable y is 0.

The graph of the parabola is attached below.
