Answer 1

A linear function is a function in which we add multiple of a constant.

Given data:

We have

`\begin{gathered} y=18,250+480(1)\text{ at x=0} \\ y=18,730=18,250+480(1)\text{ at x=1} \\ y=19,210=18,250+480(2)\text{ at x=2} \\ y=19,690=18,250+480(3)\text{ at x=3} \\ y=20,170=18,250+480(4)\text{ at x=4} \end{gathered}`

Clearly, we have add multiples of 480 to 18,250.

So, the given function represents a linear function.

So, the correct option is (a).
