The graph of a secant function shows no functional values on (−12, 12). The asymptotes of the function occur every π units. Which function represents the secant function described

f(x)=12sec(x)

f(x)=s*x(x/2)=12

f(x)=12sec(x/2)

f(x)=sec(x)+12

I tried to graph all of these but it didnt seem like any of them worked and theres no option to pick non of the above
