Answer:

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
