Answer 5

Good point :D

Answer 6

So how exactly do I find the first derivative?

Answer 7

have you had calculus?

Answer 8

First of you know what a derivative is right?

Answer 9

No, im in algebra 2

Answer 10

=.=

Answer 11

The way my teacher taught how to find the min and max is by using a calculator , but if there is an easier way by hand, I wanna know howw

Answer 12

this function is in odd degree so it has no max or min

Answer 13

How do I find the min and max using a calculator then?

Answer 14

if the function was in even degree has a max or a min or both like that i draw
