Question

Which equation is the inverse of y = 100 - x??

y=iV100- x
O y = 10 x
y= 100v
y=tVX-100

Answer 1

For this case we must find the inverse of the following function:

`y = 100-x`

To do this, we follow the steps below:

We exchange the variables:

`x = 100-y`

We clear the variable "x" (the variable is already cleared):

`x = 100-y`

We change "x" to "y":

`y = 100-x`

We change y for
`f^(-1)(x)`:

`f^(-1) (x) = 100-x`

ANswer:

`f^(-1) (x) = 100-x`
