1. The problem statement, all variables and given/known data Find the slope of the tangent to y=3x2 - 6x at x = 2 by first determining the derivative of the function from first principles 2. Relevant equations f(x+h)-f(x) / h 3. The attempt at a solution For the derivative I got -6x and the slope of the tangent is -12. Would this be correct? Thanks!
