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.
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.
