Question

8) g(n) = 3n + 2

Perform the indicated operation
f (n) = 2n
2
+ 5
Find g( f (2))

Seems simple, but I'm a little stuck. Maybe if you can explain it too, that'd be great.

Answer 1

f (n) = 2n +5 is the second bit?

Answer 2

Woops the first part and second part are supposed to be together.
8) g(n) = 3n + 2
f (n) = 2n
2
+ 5
Find g( f (2))

Answer 3

so one equation is g(n) + 3n +2 and the other is f(n) = 2n? i'm not getting what the 2 and the +5 are after

Answer 4

g(n) = 3n + 2
f (n) = 2n^2 + 5
Find g( f (2))

Answer 5

riightt
do f(2) first.

Answer 6

plug in 2 for in in the function f(n) = ...

Answer 7

2(2)^2 + 5
2*4+5
8+5

Answer 8

right, no you have g(13) left to finish it off

Answer 9
