 Question 628120: that u have to solve this problem by using differentiation and gradient at point on curves 1) At what point on the curve y=x^2+7x-8 is the gradient equal to 1 ? 2) At which points on the curve y=x^3+3x^2-5 is the gradient equal to 9 ? Answer by Alan3354(30993)   (Show Source): You can put this solution on YOUR website!1) At what point on the curve y=x^2+7x-8 is the gradient equal to 1 ? y' = 2x + 7 2x + 7 = 1 x = -3 --> (-3,-20) --------------------- 2) At which points on the curve y=x^3+3x^2-5 is the gradient equal to 9 ? y' = 3x^2 + 6x 3x^2 + 6x - 9 = 0 x^2 + 2x - 3 = 0 x = -3, 1 etc
