Question

How to calculate and/solve the inverse function of
y = 4.

Inverse Steps:

1. change 'f(x)' to 'y'
2. Flip-Flop x and y
3. Solve for y
4. Change 'y' to 'f^-1(x)'

Answer 1

inverse of y=4? no x..?

Answer 2

I'm saying how can you inverse that if there is no x value in f(x)

Answer 3

I know since it's all ready y = 4 just change the y to an x, so go to step 2 sort of

Answer 4

if you change y to x , how are you going to solve for y in the next step?

Answer 5

You need both an x and a y to get inverse of a function.

Answer 6

these steps only apply to equations which have both x and y

Answer 7

Given f(x)= 4.
Inverse Steps:
1. change 'f(x)' to 'y'
y = 4
2. Flip-Flop x and y
x = 4
3. Solve for y
Now we are stuck, there is no y here.

Answer 8

if you want the *inverse relation* of the equation y = 4
which is the ordered pairs :
(x, 4)
this will be
(4,x)

which is the equation x = 4

but this is not a function

Answer 9

@perl and @dtan5457 it's the inverse of y = 4 though, because if it's y = 4 then it's x = 4

Answer 10

Hmm no don't think so..You can't even check to see if they are inverses if you try to do (f o g)x

Answer 11

believe me it's right and the steps I put in the question are the exact ways to solve an inverse function

Answer 12

step 1 change 'f(x)' to 'y', well it's already 'y' ---> y = 4
stept 2 Flip Flop x and y, and since there is not and x, you will just replace y with x and then you are done, because you can't go any futher

Answer 13

possibly, weird question but maybe you are right.

Answer 14

in the inverse function steps I meant to add
