Graph (of a function) A visual representation of the relationship between domain and range, ie the “x-y coordinate picture” of a function.

(Cartesian) Coordinates A method of graping a function where the domain and range meet at a right angle (ie the so-called “x-y plane”.)

Precision How exact (aka how specific) a value is. For example, $2.1343435$ is more precisely determined than $2.134$ since it has considerably more digits given.

Accuracy How close to correct a value is. For example, $3.14$ is a more accurate value of $\pi$ than $3.151592$, even though $3.151592$ is a more precise number than $3.14$.

Parent Function A parent functions is the ‘prototypical’ form of the given function type. That is to say, the ‘parent function’ of a function type is the base (ie most basic) version of that function without any manipulations, shifts, or changes to it’s form.
For example: The parent function of the quadratic function would be $f(x) = x^2$. This is the base type without anything added to it.
This is most commonly referenced by asking a question. For example: ‘What is the parent function type of the function $f(x) = x^2 + 2x - 3$?’ In this case the answer would be $f(x) = x^2$ since the given function was a quadratic, and $x^2$ is the parent function for a quadratic.
