PLEASE HELP, 2 MORE QUESTIONS TRYING TO GET EXEMPT

Answer 1

@wio can you help

Answer 2

@TheSmartOne @AriPotta can one of you guys help

Answer 3

@Jesstho.-. @mathmath333 can one of you guys help

Answer 4

Can you find \(f(2)\) and \(g(2)\) first?

Answer 5

not sure what you mean

Answer 6

Well, \[
f(x) = 4x-4
\]Therefore: \[
f(2) = 4(2)-4 = 8-4 = 4
\]

Answer 7

Basically: \[
(f+3g)(2) = f(2) + 3g(2)
\]

Answer 8

And we know now that \(f(2) =4\), but we still need \(g(2)\).

Answer 9

okay, i'm following you so far.

Answer 10

i have this so far : (f + 3(x + 30^2)(2)

Answer 11

is that right so far?

Answer 12

No

Answer 13

We need to find \(g(2)\).

Answer 14

lol the rest of my work is probably wrong then..

Answer 15

Remember how I said: \[
(f+3g)(2) = f(2) + 3\,g(2)
\]

Answer 16

okay hold on let me write that down

Answer 17

okay

Answer 18

now what?

Answer 19

find \(g(2)\).

Answer 20

is it 3?

Answer 21

no

Answer 22

I think I wrote something wrong.

Answer 23

then i don't know, i've always been horrible at math.

Answer 24

\[
g(2) = ((2)+3)^2
\]

Answer 25

first add, then square

Answer 26

25?

Answer 27

Correct

Answer 28

FINALLY

Answer 29

So: \[
(f+3g)(2) = f(2) + 3\,g(2) = 4+3(25)
\]

Answer 30

okay, now what? i solve it?

Answer 31

you just simplify

Answer 32

which i never understood

Answer 33

Well \[
4+3(25) = 4+75 = 79
\]

Answer 34

thats the answer?
