Step-by-step explanation:
1. The given function is
The domain values are: x=0, 2, -1, 4, -2
When x=0
When x=2,
When x=-1
When x=4
When x=-2
2. The given function is
When x=3,
Similarly,
y = - 3
Since y varies directly as x then
y = kx ← ( k is the constant of variation )
to find k use y = - 1 when x = 3
k = =
= -
hence y = - x
when x = 9, then
y = - × 9 = - 3
