Front

Is this a Function?

Back

A function is a relation where each input has exactly one output. If an input corresponds to multiple outputs, it is not a function.

Front

Is this a Function?

Back

Yes, a function is defined as a relation where each input has exactly one output.

Front

What is the equation of the line?

Back

The equation of the line is y = 3, which indicates a horizontal line at y = 3.

Front

Calculate the rate of change.

Back

The rate of change is 6, which represents the slope of the line.

Front

Select the linear equation.

Back

A linear equation is in the form y = mx + b, where m is the slope and b is the y-intercept.

Front

What is a linear function?

Back

A linear function is a function that graphs to a straight line, defined by the equation y = mx + b.

Front

What does the slope represent in a linear equation?

Back

The slope represents the rate of change of y with respect to x, indicating how steep the line is.

Front

What is the y-intercept?

Back

The y-intercept is the point where the line crosses the y-axis, represented by the value of b in the equation y = mx + b.

Front

How do you determine if a relation is a function using the vertical line test?

Back

If a vertical line intersects the graph at more than one point, the relation is not a 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.
