## Homework Statement

Now use your answer from part (a)(This anwser is f'(25) = 7/10, which is correct) to find the equation of the tangent line to the curve at the point (25, f(25)).

## Homework Equations

f(x) = 7*sqrt(x)+3

## The Attempt at a Solution

f'(25) = 7/10

f(25) = 38

y=mx+b

38=7/10*25+b

y=7/10x + 41/2

This should be the correct answer... but it won't accept it.
