First, solve g(10)..which is just plugging in 10 for \(\sf x\).

\(\sf g(x) = x + 9\) \(\sf g(10) = 10 + 9\)

What do you get?

-9 and 0??

-9?
iGreen
  • iGreen
\(\sf 10 + 9 \ne -9~or~0\)

idk, i'm confused on this
iGreen
  • iGreen
You can't add \(\sf 10 + 9\)?
anonymous
  • anonymous
it's 19, i thought there was more to it

g(10) means we plug in 10 for 'x' in g(x) = x + 9.
iGreen
  • iGreen
Which gives us: \(\sf g(10) = 10 + 9\) Simplify: \(\sf g(10) = 19\) You're correct..now we have: \(\sf f(19)\) Plug in \(\sf 19\) for 'x' in \(\sf f(x) = 10x + 8\) now.

f(19) = 10(19) + 8? Or is it f(x) = 10x + 8
anonymous
  • anonymous
f(19) = 10x + 8*

Help
iGreen
  • iGreen
f(19) = 10(19) + 8 is correct..
iGreen
  • iGreen
\(\sf f(x) = 10x + 8\) \(\sf f(19) = 10(19) + 8\)
iGreen
  • iGreen
Now simplify the right side

  • anonymous
198 is what i got
iGreen
  • iGreen
That is correct.
