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)).
f(x) = 7*sqrt(x)+3
The Attempt at a Solution
f'(25) = 7/10
f(25) = 38
y=7/10x + 41/2
This should be the correct answer... but it won't accept it.
