Front

How is DOMAIN determined when reading a graph?

Back

DOMAIN is found by reading the ends of a graph from Left to right.

Front

What does the absolute value |x| represent?

Back

The distance of x from 0 on the number line.

Front

What is the definition of a function?

Back

A relation where each input has exactly one output.

Front

What is the difference between domain and range?

Back

Domain is the set of all possible input values, while range is the set of all possible output values.

Front

How do you find the x-intercepts of a graph?

Back

Set y = 0 and solve for x.

Front

What does it mean if a function is increasing?

Back

The output values increase as the input values increase.
