F of x equals the integral from 1 to x of the natural logarithm of t squared . Use your calculator to find f '(3)

Question

 . Use your calculator to find f '(3)

A	2.197
B	2.079
C	1.099
D	0.693

Answer 1

F(x) = ∫_{(from 1 to x)} ln(x²)dx

By the Fundamental Theorem of Calculus, F'(x) = ln(x²)

So, F'(3) = ln9 ≈ 2.197
