Answer:
10
Step-by-step explanation:
Firstly, find the value of f(3)
⇒ [tex]f(3) = 2(3) + 1[/tex] [sub in 3]
⇒ [tex]f(3) = 7[/tex] [multiply by 2 and add 1]
Now, find g(f(3))
⇒ [tex]g(f(3)) = \frac{3(7) - 1}{2}[/tex] [sub in 7]
⇒ [tex]g(f(3)) = \frac{20}{2}[/tex] [multiply by 3 and subtract 1]
⇒ [tex]g(f(3)) = 10[/tex] [divide by 2]
