Algebra & Functions

A function is a relation where each input has exactly one output.

Check if each input (x-value) corresponds to only one output (y-value). If any input has multiple outputs, it is not a function.

The degree of a polynomial is the highest power of the variable in the expression.

5x² + 5x

-8xy

g(5) = 10.

The output of a function is the value that results from applying the function to an input.

A linear function is a function that graphs to a straight line and can be expressed in the form y = mx + b.

The slope of a line is a measure of its steepness, calculated as the rise over run between two points on the line.

A polynomial is a mathematical expression that consists of variables raised to whole number powers and coefficients.
