Question

The values in the table represent a function.

A 2-column table with 5 rows. The first column is labeled x with entries negative 2, 1, 4, negative 3, 0. The second column is labeled f of x with entries 1, 3, negative 2, 0, 4.
Use the drop-down menus to complete the statements.

The ordered pair given in the first row in the table can be written using function notation as .
f(x) = –2 when x is .

Answer 2

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`.
