To be clear,[imath]x \neq 2[/imath] in interval notation is [imath]( -\infty, 2) \cup (2, \infty )[/imath].For this question, it says to "Find the domain of the following functions using interval notation".View attachment 33427 The answer is boxed, but I was wondering why the answer wasn't "x ≠ 2" since when you plug in 2 it becomes "f(x)=0" which is incorrect. Please clarify for me, thank you!
Hi sensitiverabbit. Function f is defined as a polynomial. The domain for all polynomial functions is the set of Real numbers.wondering why the answer wasn't "x ≠ 2" since when you plug in 2 it becomes "f(x)=0" which is incorrect.
