Question

When doing a Quadratic Functions how do you find maximum or minimum point

Answer 1

u must find the vertex
or find the derivative

Answer 2

I did that with a graphic calculator

Answer 3

But its confusing

Answer 4

what u did? did u find the graph?

Answer 5

Yes

Answer 6

if u have a graph u can see the vertex in there

Answer 7

well I know that my function is going up.

Answer 8

if u have something like this then u have there is a minimun point
the function does not have a maximun
un lees that is defined in a definide interval

Answer 9

so if the function is in the graph and the intervals that means that is a maximum

Answer 10

for example if the function is y=x^2 in the interval {2,3}
(a close interval)
then it is possible that the masimum occurs at the extrema point of the interval
i meant in x=2 or x=3
