Question

find the derivative of F(2)=(3/(x^2))

Answer 1

Do you mean F(x)?
\[ \frac{3}{x^2} = 3x^2 \]
Try applying the power rule to that :)

Answer 2

oops. I meant
\[ \frac{3}{x^2} = 3x^{-2} \]

Answer 3

Use the alternative form of the derivative to find the derivative of the function f(x)=(3/x^2) at x=2

Answer 4

so it would be 3/4?

Answer 5

It should be -3/4. But if they're asking you to use the alternative form, they're asking you to use the limit definition to evaluate it!

Answer 6

oh ok thank you

Answer 7

you're welcome :)
