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 .
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.
