Q1 Vocabulary: Algebra 2

Front

What is the minimum value of a function?

Back

The minimum value of a function is the lowest point on the graph, where the function's value is less than or equal to the values at all surrounding points.

Front

What type of equation has a graph that is a straight line?

Back

A linear equation is an equation whose graph is a straight line.

Front

What symbols indicate an 'OR' graph solution in absolute value inequalities?

Back

Greater Than (>) and Greater Than or Equal To (≥) indicate an 'OR' graph solution.

Front

What is interval notation?

Back

Interval notation is a way of writing subsets of a real number line, using parentheses and brackets to indicate whether endpoints are included.

Front

What does absolute value represent?

Back

Absolute value represents the distance of a number from the origin on the number line, regardless of direction.

Front

What is a linear function?

Back

A linear function is a function that can be graphically represented as a straight line, typically in the form y = mx + b.

Front

What is the difference between domain and range?

Back

The domain is the set of all possible input values (x-values) for a function, while the range is the set of all possible output values (y-values).

Front

What is a quadratic function?

Back

A quadratic function is a polynomial function of degree 2, typically in the form y = ax² + bx + c, whose graph is a parabola.

Front

What does it mean for a function to be piecewise?

Back

A piecewise function is a function that is defined by different expressions for different parts of its domain.

Front

What is the significance of the axis in a graph?

Back

The axis in a graph refers to the horizontal (x-axis) and vertical (y-axis) lines that define the coordinate system.
