Question

Differentiate f (x)
f(x) = 3/x^2 + x + 4

Answer 1

{f(x)=\frac{3}{x^2}+3}
\cr{f(x)={3}{x^{-2}}+3}\cr

Answer 2

\[{f(x)=\frac{3}{x^2}+x+4}=>{f(x)={3}{x^{-2}}+x+4}=>{f'(x)={-6}{x^{-3}+{1}}}\]

Answer 3

Last part got cut off:
\[{f'(x)={-6}{x^{-3}+{1}}}\]
(if I'm remembering my integration correctly.)
