Features of graphs

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 based on its domain.

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 does it mean for a function to be decreasing?

Back

A function is decreasing on an interval if, as the x-values increase, the y-values decrease.

Front

What is a minimum point on a graph?

Back

A minimum point is the lowest point on the graph of a function, where the function changes from decreasing to increasing.

Front

What is a y-intercept?

Back

The y-intercept is the point where the graph of a function crosses the y-axis, represented as (0, y).

Front

How do you find the range of a function from its graph?

Back

To find the range, identify the lowest and highest y-values on the graph.

Front

How do you determine the domain of a function from its graph?

Back

To determine the domain, identify the x-values for which the graph exists.

Front

What is an increasing interval?

Back

An increasing interval is a range of x-values where the function's y-values are rising.

Front

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

Back

The vertex is the highest or lowest point of the parabola, indicating the maximum or minimum value of the function.

Front

What does it mean for a function to have a horizontal asymptote?

Back

A horizontal asymptote indicates the value that the function approaches as x approaches infinity or negative infinity.
