Front

What is an absolute value function?

Back

An absolute value function is a function that outputs the non-negative value of its input. It is defined as f(x) = |x|.

Front

What is a linear function?

Back

A linear function is a function that graphs to a straight line. It can be expressed in the form f(x) = mx + b, where m is the slope and b is the y-intercept.

Front

What is a quadratic function?

Back

A quadratic function is a polynomial function of degree 2, typically in the form f(x) = ax² + bx + c, where a, b, and c are constants.

Front

What is a square root function?

Back

A square root function is a function that involves the square root of a variable, expressed as f(x) = √x.

Front

What is the parent function of a quadratic function?

Back

The parent function of a quadratic function is f(x) = x².

Front

What is the range of a quadratic function?

Back

The range of a quadratic function is all real numbers greater than or equal to the vertex's y-coordinate.

Front

What is the domain of a square root function?

Back

The domain of a square root function is all real numbers x such that x ≥ 0.

Front

What does the graph of an absolute value function look like?

Back

The graph of an absolute value function is a V-shape, opening upwards.

Front

What is the general form of a linear function?

Back

The general form of a linear function is f(x) = mx + b.

Front

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

Back

The vertex is the highest or lowest point of the parabola, depending on the direction it opens.
