Question

F(x) is a quadratic function. The graph of f(x) decreases on the

interval (-∞,-2) and increases on the interval (2,∞). It has a
y-intercept at (0, 4) . What is a possible equation for f(x)?

I am unsure about the intervals. What does the -2 and 2 mean?

Hello can you repost the question with a picture of the problem. I think the intervals are wrong.
