If f (x) = x - 5, then match each of the following.

1. f (-1) - 3

2. f (0) 0

3. f (1) - 6

4. f (2) - 5

5. f (5) - 4

6. f (8) 3

1 f (-1) = - 1-5 = - 6

2 f (0) = 0 - 5 = - 5

3 f (1) = 1 - 5 = - 4

4 f (2) = 2 - 5 = - 3

5 f (5) = 5 - 5 = 0

6 f (8) = 8 - 5 = 3

All you have to do here is to express number inside brackets instead of x and calculate it.

If for example function was f (x) = 3x + 4 than f (2) would be equal to:

f (2) = 3*2 + 4 = 6 + 4 = 10
