Question

H(n) = n + 3
g(n) = 3n
Find (h + g)(n)

Answer 1

`(h+g)(n)=4n+3`

Explanation:

So we have the two functions:

`h(n)=n+3\text{ and } g(n)=3n`

And we want to find (h+g)(n).

This is the same as: h(n)+g(n). So, substitute:

`h(n)+g(n)\\=(n+3)+(3n)`

Combine like terms:

`=4n+3`

So:

`(h+g)(n)=4n+3`

And we're done!
