Front

What is the interval of decrease for a function?

Front

What does the vertex of a parabola represent in a quadratic function?

Back

The vertex of a parabola is the highest or lowest point of the graph, depending on whether it opens upwards or downwards. For example, if the vertex is at (h, k), then the maximum or minimum value of the function occurs at y = k.

Front

What is end behavior in the context of polynomial functions?

Back

Front

What is the 'cheat code' for solving equations using technology?

Back

The 'cheat code' refers to using graphing software like Desmos to input the original equation and each answer choice to visually identify matches.

Front

What does it mean to reflect a graph across the x-axis?

Back

Reflecting a graph across the x-axis means that for every point (x, y) on the graph, there is a corresponding point (x, -y). This transformation flips the graph upside down.

Front

What is a transformation in the context of graphing functions?

Back

A transformation refers to any change made to the graph of a function, such as shifting, reflecting, stretching, or compressing.

Front

What does it mean to move a graph left or right?

Back

Moving a graph left or right involves shifting the entire graph horizontally. For example, moving a graph left 2 units means replacing x with (x + 2) in the function.

Front

What is the significance of the x-intercept in a graph?

Back

The x-intercept is the point where the graph crosses the x-axis, indicating the value of x when y = 0. It is found by solving the equation f(x) = 0.

Front

How do you determine the maximum or minimum value of a quadratic function?

Back

The maximum or minimum value of a quadratic function can be found at the vertex. If the parabola opens upwards, the vertex represents the minimum value; if it opens downwards, it represents the maximum value.
