FoA2 5.1 Features of Functions Practice

Front

What is the minimum value of a function?

Back

The minimum value of a function is the lowest point on the graph, represented by the y-value at that point.

Front

How do you find the x-intercept of a function?

Back

The x-intercept is found by setting y to 0 and solving for x.

Front

What is a function?

Back

A function is a relation where each input (x-value) has exactly one output (y-value).

Front

What are x- and y-intercepts?

Back

X-intercepts are points where the graph crosses the x-axis (y=0), and y-intercepts are points where the graph crosses the y-axis (x=0).

Front

True or False: The y-intercept of a function ALWAYS occurs where y is equal to zero.

Back

False. The y-intercept occurs where x is equal to zero.

Front

What does it mean if a graph does not represent a function?

Back

It means that at least one x-value corresponds to more than one y-value.

Front

How can you determine if a graph represents a function using the vertical line test?

Back

If a vertical line intersects the graph at more than one point, the graph does not represent a function.

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 is the domain of a function?

Back

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

Front

What is the range of a function?

Back

The range is the set of all possible output values (y-values) for the function.
