Explanation:
Hello! Remember you have to write complete question in order to get good and exact answers. Here you haven't provided any function, so I'll help you providing this one:
[tex]f(x)=3x^2+5x-6[/tex]
So [tex]f(2)[/tex] means that you need to evaluate the function when [tex]x=2[/tex]. In other words:
[tex]f(2)=3(2)^2+5(2)-6 \\ \\ f(2)=3(4)+10-6 \\ \\ f(2)=12+12-6 \\ \\ \boxed{f(2)=16}[/tex]
In this context:
Correct option is B. 16
