Question

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!

Answer 1

Too bad!

Answer 2

first of all find f(g(x)) put x=5x-1 in the function F(x) to find f(g(x))

Answer 3

i.e f(g(x))=(5x-1)+2

Answer 4

\[g(3)=5\times 3-1=15-1=14\]now find \[f(14)\]

Answer 5

\[f(14)=14+2=16\]
