Question

F(x)= 3x and g(x)= -x+4, so f(g(2))=?

Answer 1

`f(g(2))=6.`

Explanation:

We have
`g(x)=-x+4 \Rightarrow g(2)=-2+4=2`

Since
`f(x)=3x` then
`f(g(2))=f(2)=3.2=6.`

Answer 2

Answer: 6

Step-by-step explanation: first, you plug in 2 into the g(x) function. So, replace x with 2 in the second function g(x). -2 + 4 = 2. Then take that answer (2), and plug that into the x for f(x). 3 x 2 = 6
