Question

Given the functions f(x) = 6x + 11 and g(x) = x + 6, which of the following functions represents f[g(x)] correctly?

f[g(x)] = 6x + 47
f[g(x)] = 6x + 17
f[g(x)] = 6x2 + 47
f[g(x)] = 6x2 + 17

Answer 1

Can someone help explain this to me?

Answer 2

f(g(x)) means that you have to put g(x) as the value of x in f(x)

Answer 3

just replace x with x + 6

so f(x +6) = 5(x + 6) + 11

then just simplify

Answer 4

oops should be

f(x + 6) = 6(x + 6) + 11

sorry for the typo

Answer 5

so u'll have -
f(g(x)) = 6(g(x))+11
f(g(x))=6(x+6)+11
f(g(x))=6x+36+11
f(g(x))=6x+47

Answer 6

so it'd be a

Answer 7

yes

Answer 8

okay, could you help me with some more?

Answer 9

yes

Answer 10

Given the following functions f(x) and g(x), solve f[g(6)] and select the correct answer below:

f(x) = 6x + 12

g(x) = x − 8

−96
0
24
48

Answer 11

hello?

Answer 12

just find the value of

g(6) = 6 - 8

then substitute the answer into

f(x)

Answer 13

okay so g(6) = -2
then I divide?

Answer 14

then you substitute

f(-2) = 6(-2) + 12

Answer 15

oh okayyy

Answer 16

you're a huge help lol

Answer 17

can you help me with two more? @campbell_st
