You question seems incomplete.

anonymous · Answer

I'm doing well, just stressing out about learning the material. That is all the question asked. My friend is learning calc and giving me his material so I can learn a long side him.

anonymous · Answer

oh 
end is when its increasing

anonymous · Answer

f(x)= (-1/4)-(2/3)x^3+(15/2)-3 is increasing*

turingtest · Answer

and what is the test to see if a function is increasing? do you know?

turingtest · Answer

(-1/4)-(2/3)x^3+(15/2)-3
though this can be simplified first
are you sure you typed it exactly correctly?

anonymous · Answer

Yeah, I just tripled check... that's the question in its entireTY!

turingtest · Answer

then first simplify it

anonymous · Answer

-2x^2 + 15x is the derivative
