If f(x)=-3x+3, then f-1(x)=

olganol [36]

Answer: f^{-1}(x) = 3-x/3

Step-by-step explanation: Let y = f(x) and rearrange making x the subject, that is...

1. y = - 3x + 3 ( add 3x to both sides )

2. 3x + y = 3 ( subtract y from both sides )

3. 3x = 3 - y ( divide both sides by 3 )

4. x = 3-y/3

Change x back into terms of y

f^{-1}(x) = 3-x/3

DedPeter [7]

Answer:

Number of correct answers = 58

Number of incorrect answers = 22

Point scored $=58*\frac{13}{4} +22*\frac{-1}{4} =\frac{732}{4} =183$

Points need to win = 90 points

Point scored, 183 >Points need to win, 90
