Answer:

[tex]f(g(1))=15[/tex]

Step-by-step explanation:

[tex]f(x)=3x\\g(x)=x+4\\f(g(1))[/tex]

First, you need to evaluate [tex]g(1)[/tex]:

[tex]g(1)=(1)+4\\g(1)=5[/tex]

Now, you plug this into [tex]f(x)[/tex] and evaluate [tex]f(5)[/tex]:

[tex]f(5)=3(5)\\f(5)=15[/tex]

Now you know [tex]f(g(1))=15[/tex].

Answer:

f[g(1)]= 15

Step-by-step explanation:

f(x)=3x

g(x)=x+4

so you are asked to find fof(g(1))

you first find g(1)= 1+4=5

now you substitute it into f(g(1))

so you now have f(5)

f(5)= 3×5=15
