What can be said about the
continuity of the function 𝑥 cubed plus five 𝑥 squared minus two 𝑥 plus two?
Given the general rule that a
polynomial function is continuous across its domain and the domain of our function
is all of the real numbers, we can almost immediately give the following answer. The function is continuous on ℝ,
the real numbers, because it is a polynomial. This is, in fact, the quick answer
to our question.
