Answer:
f(6)=1
Step-by-step explanation:
Subsitute 
for 
in the given function.
1:a would be 3. Subtract 9 & 6 to find 3. B= 7. Again 9-2 would help you find the answer. So then it would be 3+6=7+2.
2: 2+8 gets you 10. 10+5 gets you 15. 8+5 gets you 13. 2+13 gets you 15. So it’s 15=15.
3:7 needs to be changed into a fraction so, 7/1(1/7). Multiply across, you get 7/7, which gives you 1, so it’s 1=1.
4:I’m sorry I don’t know how to do this one
5:you multiply 3 and 6x, which gives you 18x. Then multiply 3 and 9y, and you get 27y. So then you have 18x+27y=18x+27y.
6: 15+0 gets you 15. So it’s 15=15.
Hope this helped. I’m not the best at explaining
