Please help 1. Find the error & explain why it is wrong:
laural had to find the inverse of the function f(x)=-x+3. What did she do wrong?

Step A: f(x)=-x+3
Write the function

Step B: y=-x+3
Replace f(x) with y

Step C: -x=y+3
Switch the x and y values

Step D: -3-x=y
Isolate y by subtracting 3 from both sides

Step E: f^-1(x)=-3-x
State the inverse by replacing y with f^-1(x)

Step___is incorrect because . Instead, you should .

2. Find the error & explain why it is wrong:
Jon had to find the inverse of the function f(x)=6x-11. What did he do wrong?

Step A: f(x)=6x-11
Write the function

Step B: y=6x-11
Replace f(x) with y

Step C: x=6y-11
Switch the x and y values

Step D: x+11=6y
Isolate y by adding 11 to both sides

Step E: x/6+11=y
Isolate y by dividing both sides by 6

Step F: f^-1(x)=x/6+11
State the inverse by replacing y with f^-1(x)

Stepis incorrect because. Instead, you should.
