FOA U4 L2 Equations as functions & Graphing

Front

What is a function?

Back

A function is a relation where every input has only ONE output.

Front

What does the equation y = x - 6 represent?

Back

It represents a linear function where the output (y) is determined by subtracting 6 from the input (x).

Front

If the function rule is 4x, what is the output when the input is 5?

Back

The output is 20.

Front

What is the missing OUTPUT value if the function is not specified?

Back

The missing OUTPUT value can vary; in the context of the provided question, it is 9.

Front

Which point is on the graph of the function y = x?

Back

The point (0, 2) is on the graph.

Front

What is the slope of the line represented by the equation y = x - 6?

Back

The slope is 1.

Front

What does it mean for a function to be linear?

Back

A linear function creates a straight line when graphed, and it has a constant rate of change.

Front

How do you find the output of a function?

Back

Substitute the input value into the function rule.

Front

What is the y-intercept of the equation y = x - 6?

Back

The y-intercept is -6.

Front

What is the domain of a function?

Back

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