2.2 Please answer ASAP. Which of the following is ALWAYS TRUE about a function f?□ If f(x) is a rational function with denominator equal to x² + 1, then f'(x) exists for all real numbers x.O f' is defined for all x in the domain of f.If the tangent line at (c, f(c)) is vertical, then limf(c+h)-f(c)hexists.h→0□ If f(x) is a polynomial function, then f(x) is continuous at x = 0 and differentiable there.
