f(g(3)) first, find g(3) . after that, put the result tumber on the formula. like this >> f(result g(3)) do u understand?
anonymous
  • anonymous
not really.. can u help me work through this
anonymous
  • anonymous
ok.. first.. find g(3) with this formula g(x) = 5x - 1

find the result of g(3) just subtitute the x on this formula >> g(x) = 5x - 1 with 3. what is the result u got?
anonymous
  • anonymous
so substitute with x with 3
anonymous
  • anonymous
yup.

g(3) = 5(3) - 1
anonymous
  • anonymous
yup..
anonymous
  • anonymous
so 14 is the answer ?
anonymous
  • anonymous
it's the answer for g(3). now.. subtitute x with 14 to this formula f(x) = x + 2
anonymous
  • anonymous
14+2 = 16
anonymous
  • anonymous
so what now
anonymous
  • anonymous
it's the final result
anonymous
  • anonymous
so 16 is the answer not 14
anonymous
  • anonymous
can u please help me with a different question

f[g(3)] is f(g(3)) = g(3) + 2 1) to solve that first we must find g(3). g(3) = 5(3) - 1 g(3) = 15 - 1 = 14 2) after that, we can find f(g(3)). f(g(3)) = g(3) + 2 f(14) = 14 +2 f(14) = 16 do u understand?
