Answer:
#8 is equal to 6
#9 is equal to -2
#10 is equal to -1
Explanation:
If you look in the x column for 2 the outcome is 6
If you look in the f(x) column for 0 the income is -2
If you look in the f(x) column for 1.5 the income is -1
6, -2, and-1
f(2) means that x is 2, so looking in the left column find x as 2, and then find the corresponding number beside it.
f(x)=0 so look for 0 in the right column and find the number corresponding to it in the left.
