What's the difference between R and R+?
y = 18x-6x^3
find the value of x for which y is a maximum and findthe maximum value of y.
i derived the original expression and got 18-18x^2, set it equal to = and got x = -1 and x = 1. How do I know which of these values of x to substitute back into the original expression?
This question is for vce maths methods. The second derivative isn't part of the maths methods course.

Would a gradient sign test work in this instance to find the value of x for maximum and the value of x for minimum?
