Answer:

[tex]3x^2 + 8[/tex]

Step-by-step explanation:

Given functions,

[tex]f(x) = 3x + 8 ----(1)[/tex]

[tex]g(x) = x^2 -----(2)[/tex]

Since,

(fog)(x) = f( g(x) ) ( Composition of functions )

[tex]=f(x^2)[/tex] ( From equation (2) )

[tex]=3x^2 + 8[/tex] ( From equation (1) )

Hence,

[tex](fog)(x)=3x^2 + 8[/tex]

Second option is correct.
