Question

help me im timed i cant figure it out

Answer 1

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

Answer 2

Answer:

It's the third choice.

Step-by-step explanation:

f(x) = y = 4x

x = 1/4 y

Change the y to x:

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