Toolkit Functions

Constant Function

For the constant function $f(x)=c$ the domain consists of all real numbers; there are no restrictions on the input. The only output value is the constant $c$, so the range is the set $\{c\}$ that contains this single element. In interval notation, this is written as $[c,c]$, the interval that both begins and ends with $c$. Domain: Failed to parse (syntax error): {\displaystyle \( -\infty,\infty\) } Range: [c, c]
