Use the function f (x) = 2-5x to fill in the blanks in the table.

x f (x)

-2

-1

0

1

2

The function of x f (x) is just a fancy way of saying y = ...

So, y=2x-5

Now plug in what x should be to the equation:

y=2 (-2) - 5

y = - 4-5

y=-9

y = 2 (-1) - 5

y = - 2-5

y = - 7

y = 2 (0) - 5

y = 0-5

y = - 5

y = 2 (1) - 5

y = 2-5

y = - 3

y = 2 (2) - 5

y = 4-5

y = - 1

x f (x)

-2 - 9

-1 - 7

0 - 5

1 - 3

2 - 1
