Algebra 2 Final Exam

The domain of a function is the set of all possible input values (x-values) for which the function is defined. For example, if a graph shows a drone's height above the ground, the domain might be the range of distances the drone can fly.

The x-axis typically represents the independent variable, while the y-axis represents the dependent variable. In the context of a drone's flight, the x-axis could represent distance traveled, and the y-axis represents height above ground.

Reflecting a graph across the x-axis means that for every point (x, y) on the graph, there is a corresponding point (x, -y). This transformation changes the sign of the y-coordinates.

Standard form in algebra refers to writing an expression or equation in a conventional way. For polynomials, it means arranging terms in descending order of their degree.
