Question

Help me im timed i cant figure it out

Answer 1

It's the third choice.

Explanation:

f(x) = y = 4x

x = 1/4 y

Change the y to x:

so the inverse g(x) = 1/4 x.

Answer 2

For this case we have to find the inverse of a function, follow the steps below:

• Replace f (x) with y.

• We exchange the variables.

• We solve for "y".

• Finally we change y by
  `f ^ {- 1} (x)`

Then, it is observed that of option 3:

`f (x) = 4x`

Replace
`f (x)`with y:

`y = 4x`

We exchange the variables:

`x = 4y`

We solve for "y":

`4y = x\\y = \frac {x} {4}`

Finally we change y by
`f ^ {- 1} (x):`

`f ^ {- 1} (x) = \frac {x} {4}`

Answer:

The correct option is C
