These are all concave up parabolas.

they are parabolas becasue the highest power of x (the degree) for each one is 2

They are all concave up becasue the number in front of x^2 (the leading coefficient) is positve.

 

The higher the leading coefficient the steeper, or narrower, the parabola.

Now you can work if out for yourself.
