a parabola has and axis of symmetry of x=2 and a range of all real numbers less than or equal to -4. which equation represents this parabola?

Question

y=(x+2)^2-4

y=(x-2)^2-4

y=-(x+2)^2-4

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

Answer 1

Since the range is numbers less than -4, the coefficient of the squared term must be negative.

That makes y=-(x-2)²-4 the only choice.
