ALGEBRA 2 1ST SEMESTER FINAL

Front

What are the x-intercepts of a function?

Back

The x-intercepts, also known as the roots, zeroes, and solutions, are the points where the graph of the function intersects the x-axis.

Front

What does the 'k' value represent in the vertex form of a quadratic function f(x) = a(x - h)² + k?

Back

The 'k' value shifts the graph of the function up or down.

Front

How do you write an ordered pair?

Back

An ordered pair is written as (X, Y).

Front

What is the domain of a function?

Back

The domain of a function consists of all possible x-values that can be input into the function.

Front

How do you find the value of a function at a specific point, such as f(0) for f(x) = -3(x-1)?

Back

To find f(0), substitute 0 for x in the function and simplify.

Front

What is the range of a function?

Back

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

Front

What is the vertex of a parabola in the context of quadratic functions?

Back

The vertex is the highest or lowest point of the parabola, depending on its orientation.

Front

What does the 'a' value indicate in the vertex form of a quadratic function?

Back

The 'a' value determines the direction of the parabola (upward if a > 0, downward if a < 0) and its width.

Front

How can you determine if a quadratic function opens upwards or downwards?

Back

If the 'a' value in the vertex form is positive, the parabola opens upwards; if negative, it opens downwards.

Front

What is the significance of the h value in the vertex form of a quadratic function?

Back

The 'h' value represents the x-coordinate of the vertex and indicates horizontal shifts of the graph.
