RE:I have 3 problems I'm struggling with. Any help would be great
1) Given the function below
-Find the equation of the tangent line to the graph of the function at x=1. Answer in mx+b form.
(Now, I found the derivative (100x^2)/(100x^3+25)^2/3. I then plugged 1 in as x and got 4, and when putting it into the point-slope form equation, I get 4x. But for some reason, the test I'm taking is telling me this is wrong, so I'm stumped already.)
The rest goes..
-Use the tangent line to approximate f(1.1).
-Compute the actual value of f(1.1). What is the error between the function value and the linear approximation?
Answer as a positive value only. Approximate to 5 decimal places.
