Answer:
C.
Step-by-step explanation:
The rate of change of a linear function is usually constant and the same between any two coordinate pairs all through.
Rate of change is given as ∆y/∆x.
For the table in option C, the rate of change is constant all through.
We have: (12 - 8)/(3 - 2) = (16 - 12)/(4 - 3) = (20 - 16)/(5 - 4) = 4
Rate of change of constant all through. If we graph the table of values, we'd get a straight line.
Therefore, the table in option C represents a linear function.
