Math Problem Statement
Find the equation of the tangent line at (2, f(2)) when f(2) = 13 and f'(2) = 4.
Solution
To find the equation of the tangent line at the point given and , we use the point-slope form of a line:
where:
- is the point on the curve.
- is the slope of the tangent line, which is given by the derivative at .
