That's it.

Answer:
The mean temperature is O
Step-by-step explanation:
All you have to do here is replace f(x) with x + 2 and h(x) with 1/x-1.
It's like plugging in a number for x, but instead you are plugging in a whole function instead of just a number. Whenever you are pluging something in, whatever it is, make sure it is in parentheses: ( ) always!
Until your understanding of algebra becomes stronger.
2f(x)-hx
First lets plug in x + 2 for f(x). It's gonna look like this:
2(x + 2) - h(x)
Notice how I put x + 2 in parentheses next to the 2, you
a l w a y s want to do this. Now we just do the same for h(x):
2(x + 2) - (1/x - 1)
And that's it. That's all you have to do.
