Rewrite each parabola equation in vertex form. Use "y=..." format, no spaces.

Watch this video to review how to find a parabola's vertex form.

y = x^{2} + 4x - 1

Review: for the following parabolas, find the function features.

These will only turn green when you get all parts correct.

f(x) = x^{2}+4x-7

The vertex is at

The axis of symmetry is

The function is decreasing on the interval

As x\rightarrow -\infty, f(x) \rightarrow

The vertex is a

The function is increasing on the interval

As x\rightarrow\infty, f(x) \rightarrow
