Question

Let f(x) = -4x + 7 and g(x) = 10x - 6, find f(g(x)).

Answer 1

just plug it in, all your doing is switching the sign and then solving

Answer 2

yeah that's what I don't get

Answer 3

fgt

Answer 4

Whats fgt?

Answer 5

a not so good word

Answer 6

maybe he should hop his azz out of here, if he aint got nothin better to say

Answer 7

he did

Answer 8

im backkk ;)

Answer 9

\[\Large f(\color{royalblue}{x})=-4\color{royalblue}{x}+7\]

Plug g(x) into our blue x here.\[\Large f(\color{royalblue}{g(x)})=-4\color{royalblue}{g(x)}+7\]
Plugging the actual function in on the right gives us,\[\Large f(\color{royalblue}{g(x)})=-4\color{royalblue}{(10x-6)}+7\]

Answer 10

nobody give a F***

Answer 11

so would it be -40x+64

Answer 12

Hmm let's see.\[\Large f(g(x))=-4(10x-6)+7\]
Distributing the -4 to each term in the brackets gives us,\[\Large f(g(x))=-40x+24+7\]
