Question

Which statement correctly describes the function?
f(x)= x+4/ x^2+7x+10
A. It is continuous.
B. It is discontinuous because there is a value a for which f(a) is not defined.
C. It is discontinuous because there is a value a such that lim x->a f(x) does not equal f(a).
D. It is discontinuous because there is a value a such that lim x->a f(x) does not exist.
