Answer:

$f^{-1}$ (x) = x + 7

Step-by-step explanation:

Let y = f(x) and rearrange making x the subject, that is

y = x - 7 ( add 7 to both sides )

y + 7 = x

change y back into terms of x, then

$f^{-1}$ (x) = x + 7

The values in the table represent a function.

Hatshy [7]

Given:

The values in the table represent a function.

x f(x)

-2 1

1 3

4 -2

-3 0

0 4

To find:

Function notation for the ordered pair given in the first row in the table.

Solution:

We know that, if a point (a,b) is on the function, then $f(a)=b$ .

From the given table, the ordered pair given in the first row is (-2,1). So,

$f(-2)=1$

Therefore, $f(x)=1$ when $x$ is $-2$ .
