I found the derivative, and set it equal to zero, but 1 was not one of the values i got... :(

Ya the answer key is incorrect, it appears to have a max at \(x=\dfrac{4}{3}\). I keep getting x=3/4 when I work it out though, so I gotta figure out where my mistake is.

OH the problem was probably SUPPOSE TO BE,\[\large f(x)=\frac{x^4}{\color{salmon}4}-\frac{x^5}{5}\]

Because that clearly gives a critical point at x=1
