i tried and got 0

can you show me how to solve with working please.

thank you!

dy/dx=6x-1 So when x=1 gradient of tangent=5 Also when x=1 y=2+e

So you want a straight line with gradient 5 through the point (1,2+e) - April 17th 2012, 01:42 AMa tutorRe: tangent line curve

So now dy/dx=6x-e^1-x When x=1 y=4 and dy/dx=5 Require straight line through (1,4) with gradient 5
