Front

What is an Absolute Value Function?

Back

A function of the form f(x) = |x|, where f(x) is always non-negative.

Front

What defines a One-to-One Function?

Back

A function where every element of the range is paired with exactly one element of the domain.

Front

What does it mean for a function to be Onto?

Back

A function is onto if every element in the codomain is mapped by at least one element from the domain.

Front

What is the definition of a Discrete Function?

Back

A function that has distinct and separate values, often represented by individual points.

Front

What is a Step Function?

Back

A piecewise constant function that jumps from one value to another without taking on values in between.

Front

What is the difference between Point Symmetry and Line Symmetry?

Back

Point symmetry means the graph is symmetric about a point, while line symmetry means it is symmetric about a line.

Front

How can you identify if a graph is One-to-One?

Back

A graph is one-to-one if any horizontal line intersects it at most once.

Front

What is Line Symmetry?

Back

A graph has line symmetry if it can be folded along a line and both halves match.

Front

What is Point Symmetry?

Back

A graph has point symmetry if it looks the same when rotated 180 degrees around a point.

Front

What is a Constant Function?

Back

A function that always returns the same value regardless of the input.
