Y=2x^2

(x,y)(-6,72)(-3,18)(0,0)(2,8)(4,32)

You can tell that the graph opens up because in the original equation the A term is positive. You can also tell it opens up because none of the y terms in the table are negative.

Y=-x^2+16

A Rainbow is a good example of a real life downward opening porabola. The rainbow increases from the left to the middle and decreses from the middle to the left.

(x,y)(-3,-20)(-4,0)(-2,12)(0,16)(4,0)(3,-20)

You can tell that this prabola will open down because in the original equation the a term in negative. Also you can tell because the coordinates in the table go from negative to positive and back to negative.

Deer antlers are a good example of a real life upward opening porabola. the antlers come down from the tips of the points on the antlers to just above the middle of the head.
