Front

What is a system of equations?

Back

A set of two or more equations with the same variables that can be solved together.

Front

How do you represent a linear function?

Back

A linear function can be represented by an equation of the form f(x) = mx + b, where m is the slope and b is the y-intercept.

Front

What is the domain of a function?

Back

The domain of a function is the set of all possible input values (x-values) for which the function is defined.

Front

What is the range of a function?

Back

The range of a function is the set of all possible output values (y-values) that the function can produce.

Front

What does it mean for a function to be linear?

Back

A function is linear if its graph is a straight line, which means it has a constant rate of change.

Front

What are the roots of a quadratic equation?

Back

The roots of a quadratic equation are the values of x that make the equation equal to zero.

Front

How do you find the roots of a quadratic equation?

Back

You can find the roots of a quadratic equation using factoring, completing the square, or the quadratic formula: x = (-b ± √(b²-4ac)) / (2a).

Front

What is the quadratic formula?

Back

The quadratic formula is x = (-b ± √(b²-4ac)) / (2a), used to find the roots of a quadratic equation ax² + bx + c = 0.

Front

What is the slope-intercept form of a linear equation?

Back

The slope-intercept form is y = mx + b, where m is the slope and b is the y-intercept.

Front

What does it mean for two lines to be parallel?

Back

Two lines are parallel if they have the same slope and will never intersect.
