A function is increasing on an interval if the output values rise as the input values increase. It is decreasing if the output values fall as the input values increase.

What is the end behavior of a parabola?

Back

The end behavior of a parabola describes how the function behaves as x approaches positive or negative infinity. For a parabola that opens upwards, as x -> ±∞, f(x) -> +∞. For a parabola that opens downwards, as x -> ±∞, f(x) -> -∞.
