Have you learned how to differentiate? f'(x) gives the slope of the tangent to f(x) at any x point.
Thank you. :3
It's correct. Now, f'(1) will give you the slope at x=1. Then you can use the general line formula, We know that m = slope = f'(1). And the line must pass the point . Using these, find C. There, you have the equation
