Which statement correctly describes the function?
 f(x)=
 [6x-5, ifx>0
 2x-10, ifx≤0
 OA. It is continuous.
 OB. It is discontinuous because there is a value for a for which f(a) is not defined.
 OC. It is discontinuous because there is a value of a such that lim f(x) = f(a).
 X-a
 OD. It is discontinuous because there is a value for a such that lim f(x) does not exist.
