Answer 1

Option A is correct.

`D(x)=x^2+497x+394`

Explanations:

Given the following functions based on income generated

Income generated from first job M(x) = 400x + 394

Income generated from the second job A(x)= x^2 + 97x

Calculate the total income;

The total income of the function is the sum of both income functions above as shown:

`\begin{gathered} D(x)=M(x)+A(x) \\ D(x)=400x+394+(x^2+97x) \\ D(x)=x^2+400x+97x+394 \\ D(x)=x^2+497x+394 \end{gathered}`

This function D(x) gives the resulting function that represent the total income.
