Ok im in a situation where im stuck. The highest points on my parabola are (8,30) and (9,30) so do i say there is no vertex or do i say that these are both the highest points. There is not just one point where everything meets up there are two points

I think I know what you're doing wrong. You're only plugging in integer values for x, so you're missing the fact that they're something even higher at x = 8.5 (like others have already answered you). If that is in fact what you're doing, you can get the x-coordinate of the vertex by calculating -b/2a (when the equation is given in the form y = ax² + bx + c )

All parabolas have a vertex. The highest point is actually midway between x = 8 and x = 9. Its coordinates are of the form:
(8.5, y)
Without more information I can not say what y would be.

I'd have to say that there is another, higher point at x = 8.5. Unless of course you don't actually have a parabola and instead some cubic or higher function, in which case you can have local maximums at both points. Just take your equation and plug in 8.5 for x and see what y value you get.

Try (8.5,Y Value) 8.5 is between 8 and 9. All parabolas have vretexes. If there was no vertex then it would not be a parabola.

What is the equation?
and all parabolas have a vertex, so i think your data might be a little messed up

A parabola cannot have two relative maxima. There is an error in your data, or your curve is not a parbola. Can you give us more information so we can help sort this out for you?

There should be one point. IM me with the parabola's equation if you want to see if we can figure it out.

What is the value at 8.5?
