Consider the function y = B(x) such that B(12) = 3 and B'(12) = - -. Find the slope m of the tangent line to the graph of y = B(x) at x = 12. m = Find the point of intersection of y = B(x) and its tangent line at x = 12. ( x, y ) = Find an equation of the tangent line of y = B(x) at x = 12. Need Help? Read It
