Step-by-step explanation:
1. The given function is
[tex]f(x) = - 3x[/tex]
The domain values are: x=0, 2, -1, 4, -2
When x=0
[tex]f(0) = - 3 \times 0 = 0[/tex]
When x=2,
[tex]f(x) = - 3 \times 2 = - 6[/tex]
When x=-1
[tex]f(x) = - 3 \times - 1 = 3[/tex]
When x=4
[tex]f(4) = - 3 \times 4 = - 12[/tex]
When x=-2
[tex]f( - 2) = - 3 \times - 2 = 6[/tex]
2. The given function is
[tex]f(x) = \frac{1}{3} x[/tex]
When x=3,
[tex]f(3) = \frac{1}{3} \times 3 = 1[/tex]
Similarly,
[tex]f( - 3) = \frac{1}{3} \times - 3 = - 1[/tex]
[tex]f(300) = \frac{1}{3} \times 300 = 100[/tex]
[tex]f( - 180) = \frac{1}{3} \times - 180 = - 60[/tex]
[tex]f(99) = \frac{1}{3} \times 99 = 33[/tex]
