Question

Help Please?!

Let f(x) = 9x - 2 and g(x) = -x + 3. Find f(g(x)).

-9x - 2
-9x + 5
-9x + 25
-9x + 27

Answer 1

\(\normalsize\color{black}{ f(x) = 9x - 2\LARGE\color{white}{ \rm │ }}\)
\(\normalsize\color{black}{ f(g) = \color{magenta}{-x+3}\LARGE\color{white}{ \rm │ }}\)

\(\normalsize\color{black}{ f(g(x)) = 9(\color{magenta}{-x+3}) - 2\LARGE\color{white}{ \rm │ }}\)

Answer 2

can you finish it from here ?

Answer 3

I'm not sure but I can try, Thank you

Answer 4

well, you know what \(\normalsize\color{black}{ 9(-x+3)}\) is going to be, and then just subtract 2 from that.

Answer 5

So A?

Answer 6

no

Answer 7

Can you first tell me what 9(-x+3) will be after expanding the parenthesis ?

Answer 8

6 (-x) I don't exactly know what I'm doing sorry.
