KP ALG2 QSE #2 Review (All TEKS)

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 defined for all real numbers?

Back

It means that the function can accept any real number as an input, and there are no restrictions on the x-values.

Front

How do you determine the domain of a quadratic function?

Back

The domain of a quadratic function is always all real numbers, expressed as (-∞, ∞).

Front

What is the vertex form of a quadratic function?

Back

Front

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

Back

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

Front

How do you find the range of a quadratic function in vertex form?

Back

If the parabola opens upwards (a > 0), the range is [k, ∞). If it opens downwards (a < 0), the range is (-∞, k].

Front

What is a system of equations?

Back

A system of equations is a set of two or more equations with the same variables that are solved together.

Front

What does it mean for a system of equations to have no solution?

Back

It means that the equations represent parallel lines that never intersect, indicating that there are no common solutions.
