The vertex is the maximum point

The vertex is the minimum point

Has no x-intercepts

Has 1 x-intercept

Has 2 x-intercepts

Travels through the origin

As x increases y increases until it reaches the vertex, then as x increases, y decreases

As x increases y decreases until it reaches the vertex, then as x increases, y increases
