Question

Gerald has two freelance jobs. The income he can make from his first job can be represented by the function m(x)=408x+327 where x is the number of weeks he works the income he can make from his second job is represented by the function a(x)=x^2+61x. Which function best describes d(x) the income he can make from both jobs

Answer 1

d(x) =
`x^(2)` + 469x + 327

Explanation:

m(x)=408x+327 First job

a(x)=
`x^(2)`+61x Second job

To create a function to describe the income from both jobs, we would add the functions together.

d(x) =
`x^(2)` + 61x + 408x + 327 Add like terms

d(x) =
`x^(2)` + 469x + 327
