Question

how do you write X Cannot Equal 6 in interval notation?

Answer 1

Take the interval

\[\Large (-\infty, \infty) \]

which is the set of all real numbers

and "poke a hole in it" so to speak to get this

\[\Large (-\infty, 6) \cup (6, \infty) \]

Answer 2

another way to see it: you're taking the set of numbers that's less than 6 and combining it with the set of numbers that are greater than 6

we're not including the actual value of 6

Okay thank you so much (:
