## rebecca1233 3 years ago What is the value of f[g(3)] for the functions f(x) = x + 2 and g(x) = 5x - 1? (Type only the value of your final answer, no variables.) Numerical Answers Expected!

1. febylailani

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?

2. rebecca1233

not really.. can u help me work through this

3. febylailani

ok.. first.. find g(3) with this formula g(x) = 5x - 1

4. rebecca1233

soo what do i do now..

5. febylailani

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?

6. rebecca1233

so substitute with x with 3

7. febylailani

yup.

8. rebecca1233

g(3) = 5(3) - 1

9. febylailani

yup..

10. rebecca1233

so 14 is the answer ?

11. febylailani

it's the answer for g(3). now.. subtitute x with 14 to this formula f(x) = x + 2

12. rebecca1233

14+2 = 16

13. rebecca1233

so what now

14. febylailani

it's the final result

15. rebecca1233

so 16 is the answer not 14
