What is a function?

Back

A function is a relation between a set of inputs and a set of possible outputs where each input is related to exactly one output.

Front

What is the end behavior of a graph?

Back

The end behavior of a graph describes how the values of the function behave as the input approaches positive or negative infinity.

Front

What is an Absolute Value function?

Back

An Absolute Value function is a piecewise function defined as f(x) = |x|, which outputs the non-negative value of x.

Back

Front

What is the significance of the vertex in a quadratic function?

Back

The vertex represents the maximum or minimum point of the parabola, depending on the direction it opens.

Front

What does the inequality y < -|x| + 3 represent graphically?

Back

This inequality represents the region below the V-shaped graph of the absolute value function shifted down by 3 units.

Front

What is the difference between a linear equation and a linear inequality?

Back

A linear equation represents a straight line, while a linear inequality represents a region of the plane that satisfies the inequality.

Front

What is the general form of a linear equation?

Front

What does it mean for a function to be increasing?

Back

A function is increasing on an interval if, for any two points in that interval, the function value at the second point is greater than the function value at the first point.
