None
The Attempt at a Solution
Well first you have to get the derivative of the function which is 6x-1...Then what? There are no points given...I tried solving in terms of x and plugging it back in the equation but it didn't work:
x=(m+1)/6 and y=6x^(2)-x+1...I tried substituting these but nothing happened...Any ideas?
