Question

Which of the following describes the graph of {x | 2 < x < 2}?

just a closed circle on 2
an open circle on 2 and arrows pointing out
the entire number line
no solution

Answer 1

{x | 2 < x < 2} another way of saying \(\begin{array}{llll}
2<x\qquad \textit{"x" is less than 2}\\
2>x\qquad \textit{"x" is more than 2}\\
\textit{less than and more than BUT }\ne 2
\end{array}\)

so... what do you think?

Answer 2

hmm I got it a bit backwards, lemme fix it

{x | 2 < x < 2} another way of saying \(\begin{array}{llll}
2<x\qquad \textit{"x" is more than 2}\\
2>x\qquad \textit{"x" is less than 2}\\
\textit{less than and more than BUT }\ne 2
\end{array}\)
there, what do you think?
