Graphing functions with calculus
I am stuck on graphing y = ( x 3 ) x
I am pretty sure that the domain is all positive numbers including zero. The y intercept is 0, x is 0 and 3.
There are no asymptotes or symmetry.
Finding the interval of increase or decrease I take the derivative which will give me x + x 3 2 x .
Finding zeroes for this I subtract x and then multiply by the denominator 2 x = x 3.
This gives me 3 as a zero, but this isn't correct according to the book so I am stuck. I am not sure what is wrong.
