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.

The

step-by-step explanation:

i think something is missing in your question because y-1=(x-12) would not pass through the point (-4,-3). because if you replace x by -4 your are supposed to find y=-3 which is not the case her. if you replace x by -4 you find =-15.

i assume the right equation is y-1=1/4*(x-12) because this one is passing through both your points (if you are interested to know how i found that out i can tell you).

in this equation if i replace x by -4 i find y=-3 and if i replace x by 12, i find y=1 so the line representing this equation is passing through those 2 points.

then the standard form of the equation is finding an expression of y in function of x

y-1=1/4*(x-12)

y=x/4-3+1

y=x/4-2

hope that .

do you confirm there was a mistake in the question?

should have been evaluated with one odd value and one even value. the expressions have equivalent values when . when , the first expression has a value of 3 and the second

i think its 7.6
