Unit 3 Practice

Front

What is the domain in a function?

Back

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

Front

What does the y-intercept represent in a graph?

Back

The y-intercept is the point where the graph intersects the y-axis, representing the value of the function when x=0.

Front

What is the range in a function?

Back

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

Front

How do you find the value of a function at a specific point, such as d(12)?

Back

To find d(12), substitute x=12 into the function and solve for y.

Front

What is the minimum value in a graph?

Back

The minimum value is the lowest point on the graph, representing the smallest output value of the function.

Front

What does it mean if a function is defined on the interval [0, 16]?

Back

It means that the function is valid for all x-values from 0 to 16, inclusive.

Front

How can you determine the maximum value from a graph?

Back

The maximum value is the highest point on the graph, representing the largest output value of the function.

Front

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

Back

The x-axis represents the input values (independent variable) of the function.

Front

What is the significance of the y-axis in a graph?

Back

The y-axis represents the output values (dependent variable) of the function.

Front

What does it mean for a function to be continuous?

Back

A function is continuous if there are no breaks, jumps, or holes in its graph.
