Question

Find the intervals on which the following function is increasing and on which it is decreasing f(x) = (x^2+49)/(x)

Answer 1

you will need to find the derivative of the function

Answer 2

can you find f'(x) for me or need help?

\(\large\color{slate}{ ( }\)if you want you can re-write it as x + (49/x) and apply the power rule to each term. Instead of using quotient. \(\large\color{slate}{) }\)

Answer 3

This is what I have for the derivative.
(x^2+49)(-1(x)^-2)+(2x)(x^-2)

Answer 4

missued the quotient rule, I think
