Answer:
26 days
Step-by-step explanation:
If 6 days = rs. 2130
then 1 day = (2130 × 1) ÷ 6
Therefore 1 day = rs 355
For rs. 9230, the number of days he worked:
= 9230 ÷ 355
= 26 days
Answer: f^ -1 = x-9/2
Explanation & Steps:
1) Change f(x) to y
2) Switch y and x -> you will get x= y + 9/2
3) subtract 9/2 on both sides -> you will get x-9/2= y
Result- y = x-9/2
(Switch y to f^-1)
