Front

What is a function?

Back

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

Front

How do you read f(x)?

Back

f(x) is read as 'f of x'.

Front

Determine the value of x given f(x) = 10. If f(x) = 10 when x = ?

Back

x = 30.

Front

Use the graph to solve f(x) = 4. What is the value of x?

Back

x = 2.

Front

Given the graph, find f(x) = 1. What is the value of x?

Back

x = 6.6.

Front

What is the domain of a function?

Back

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

Front

What is the range of a function?

Back

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

Front

What does it mean for a function to be one-to-one?

Back

A function is one-to-one if every output is produced by exactly one input.

Front

What is a linear function?

Back

A linear function is a function that graphs to a straight line and can be expressed in the form f(x) = mx + b.

Front

What is the slope of a line?

Back

The slope is a measure of the steepness of a line, calculated as the change in y over the change in x (rise/run).
