Flex tables

Function value table

The flex-table below uses the class function-table to render the value table of \(f(x)=2x+1\).

\(x\)	\(0\)	\(1\)	\(2\)	\(3\)	\(4\)
\(f(x)\)	\(1\)	\(3\)	\(5\)	\(7\)	\(9\)

Function sign table

The flex-table below uses the class function-table to render the sign table of \(f(x)=\dfrac{\sqrt{-x+2}}{2x(2x+1)}\).

\(x\)	\(\tiny-\;\infty\)	\(-\frac{1}{2}\)		\(0\)		\(2\)	\(\tiny+\;\infty\)
\(\sqrt{-x+2}\)	\(+\)		\(+\)		\(+\)	\(0\)
\(2x\)	\(-\)		\(-\)	\(0\)	\(+\)		\(+\)
\(2x+1\)	\(-\)	\(0\)	\(+\)		\(+\)		\(+\)
\(\dfrac{\sqrt{-x+2}}{2x(2x+1)}\)	\(+\)		\(-\)		\(+\)	\(0\)
