Answer:
The answer is 4
Step-by-step explanation:
Step one:
given that the functions are
f(x)=√x+3,
g(x)=2x+9,
h(x)=x4 .
To Evaluate f(g(2)) , we need to find g(x=2)=2x+9,
substitute x=2 in g(x)=2x+9,
g(x=2)=2(2)+9,
g(x=2)=4+9,
g(x=2)=13
Step two:
now we can substitute g(x)= 13 in the function f(x)=√x+3
that is x=13
f(g(2)) =√g(x)+3--------g(x)=13
f(g(2)) =√13+3
f(g(2)) =√16
f(g(2)) =4
Hence f(g(2)) is 4
