Question

PLEASE HELP! I GUESS IT'S,C,Find the maximum and minimum values of the function 3x'square-2x'cube.[A=3,0] [B=2,0][C=1,0]

Answer 1

I read that your function is
f(x) = 3x^2 - 2x^3

and I will assume that [A=3,0] [B=2,0][C=1,0] are your answers stated in an unusual way.

lets' see ....
f ' (x) = 6x - 6x^2
for a max/min this equals zero
6x + 6x^2 = 0
6x( 1- x) = 0
x = 0 or x = 1

f(0) = 3(0) - 2(0) = 0
f(1) = 3(1) - 2(1) = 1

the max is (1,1), the min is (0,0)

check:

I have no idea what that other stuff is.
