Option B: [tex]6x^2-10x+19[/tex] is the correct answer

Step-by-step explanation:

Given functions are:

[tex]f(x) = 3x^2-5x+13\\g(x) = 2x-7[/tex]

We have to find g(f(x))

So,

[tex]g(f(x)) = 2(f(x))-7\\= 2(3x^2-5x+13)-7\\=6x^2-10x+26-7\\= 6x^2-10x+19[/tex]

Hence,

Option B: [tex]6x^2-10x+19[/tex] is the correct answer
