Question

Given the functions:
g(n) = 3n - 5
f(n) = n2 + 50
Find:
(g+f)(8)

Answer 1

Answer:

$(g + f)(8) =133$

Step-by-step explanation:

Given

$g(n) = 3n - 5$

$f(n) = n^2 + 50$

Required

$(g + f)(8)$

This is calculated as:

$(g + f)(n) =g(n) + f(n)$

So, we have:

$(g + f)(n) =3n - 5 + n^2 +50$

$Substitute$ 8 for n

$(g + f)(8) =3*8 - 5 + 8^2 +50$

$(g + f)(8) =24 - 5 + 64 +50$

$(g + f)(8) =133$
