Given F(x)=1/x-4, g(x)=1/6-x. Find f+g(x).
Yakvenalex [24]

\boxed{f(x)+g(x)=\frac{1}{x}-x-\frac{23}{6}}

<h2>Explanation:</h2>

We are given two functions:

f(x)=\frac{1}{4}x-4 \\ \\ g(x)=\frac{1}{6}-x

So, we have to find f(x)+g(x) which is the sum of these two functions:

f(x)+g(x)=\frac{1}{x}-4+\frac{1}{6}-x \\ \\ \\ Let's \ call \ h(x)=f(x)+g(x) \\ \\ Simplifying: \\ \\ h(x)=\left(\frac{1}{x}-x)+(-4+\frac{1}{6}) \\ \\ \\ \\

Finally: \\ \\ \boxed{f(x)+g(x)=\frac{1}{x}-x-\frac{23}{6}}
