Question

Calculate f(x) for the given domain values.

1. f(x)= -3x; x=0, 2, -1, 4, -2

2. f(x)=1/3x; x=3, -3, 300, -180, 99

Answer 1

See explanation

Explanation:

1. The given function is

`f(x) = - 3x`

The domain values are: x=0, 2, -1, 4, -2

When x=0

`f(0) = - 3 * 0 = 0`

When x=2,

`f(x) = - 3 * 2 = - 6`

When x=-1

`f(x) = - 3 * - 1 = 3`

When x=4

`f(4) = - 3 * 4 = - 12`

When x=-2

`f( - 2) = - 3 * - 2 = 6`

2. The given function is

`f(x) = (1)/(3) x`

When x=3,

`f(3) = (1)/(3) * 3 = 1`

Similarly,

`f( - 3) = (1)/(3) * - 3 = - 1`

`f(300) = (1)/(3) * 300 = 100`

`f( - 180) = (1)/(3) * - 180 = - 60`

`f(99) = (1)/(3) * 99 = 33`
