For the function f (x) = 2x2 - 11x - 2, find the equation of the tangent line at 7=-1.Given f($) = 3 see2 (er) , write the equation of the line tangent tn 3; = f (:12) when 113 = U. Determine the values of a and b which would result in the function f (@) being differentiable at x = -1. f (z ) 2ax + 6 for *
