Question

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

Answer 1

Answer:

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

Step-by-step 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!
