A function $f(x)$ is a relation between a set of inputs (called the domain) and a set of possible outputs (called the range).
The derivative of a function $f(x)$ is denoted by $f'(x)$ and represents the rate of change of the function with respect to $x$.
A parametric equation is a set of equations that express $x$ and $y$ in terms of a parameter $t$.
A function $f(x)$ is increasing on an interval if $f'(x) > 0$ for all $x$ in the interval.
