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.

<u>Answer:</u>
<u>Solution:</u>
This method can be used to find any percentage!
- 206 x 40 = 8240
- 8240 ÷ 100 = 82.4

If the point ( 8,-2) is on F(X) that a point ( -2,8) must be on the graph of the inverse fraction F^-1 (x) because the invers of a function is found by inversing the coordinate x and y.
so first you need to find the slop between (1,3) and (4,5)
5-3/ 4-1 = 2/ 3= m
using that slope you put it into the slope intercept formula
y=mx+b
use the coordinate (2,-5)
-5= 2/3 (2)+b
-5= 1.33+b subtract 1.33 on both sides
-6.33=b
plug b and m into the slope intercept formula
ANSWER: y=2/3x-6.33
