A rational function \( h(x) = {f(x) \over g(x)} \) is continuous at x = a if what condition is satisfied? 

 

a) f(a) and g(a) are both defined

b) g(a) is defined

c) g(a) ≠ 0

d) f(a) ≠ 0 and g(a) ≠ 0

 

I believe the answer is A.

Based on the following, I believe "c"  is correct :

 

(ii.) Every rational function is continuous everywhere it is defined, i.e., at every point in its domain. Its only discontinuities occur at the zeros of its denominator.
