Solution:
we are given that
If G is the midpoint of FH, it mean that

we are also given that

So we can write

So 
The taxes on an item costs $164 *4,7/%
T=$7,78
Answer:
f^-1(x) = x+1
Step-by-step explanation:
turn into y = x-1
1. Flip x to y and y to x
x = y-1
2. isolate y
x+1 = y
using a graph you can find it by reflecting x-1 over y=x
A should be the correct answer. Let me know if I’m right!
