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 6, 7, 4, 3, negative 5. The second column is labeled f of x with entries 8, 3, negative 5, negative 2, 12.

Use the drop-down menus to complete the statements.

The ordered pair given in the first row of the table can be written using function notation as.

f(3) is.

f(x) = –5 when x is.

Answer 1

f(3) is -2

f(x) = -5 when x is 4

Answer 2

f(-6) = 8

f(3) = -2

f(x) = -5 when x is 4

Explanation:

* Lets explain how to solve the problem

- The table of the function has two column

# First column labeled x with entries:

-6 , 7 , 4 , 3 , -5

# Second column labeled f(x) with entries:

8 , 3 , -5 , -2 , 12

∴ The ordered pairs of the function f(x) are:

(-6 , 8) , (7 , 3) , (4 , -5) , (3 , -2) , (-5 , 12)

* Lets complete the missing

∵ The value of x in the first row is -6

∵ The value of f(x) in the first row is 8

∴ The function notation in the 1st row is f(-6) = 8

- The ordered pair given in the first row of the table can be

written using function notation as f(-6) = 8

∵ The ordered pair whose x = 3 is (3 , -2)

∴ The value of f(x) when x = 3 is -2

∴ f(3) = -2

∵ The ordered pair whose f(x) = -5 is (4 , -5)

∴ The value of x when f(x) = -5 is 4

∴ f(x) = -5 when x is 4
