Back

x = -5

Front

Evaluate the function for the given value: f(0) = ?

Back

1

Front

What is the definition of a function?

Back

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

Front

Evaluate the function for the given value: f(2) = ?

Back

f(2) = -4

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

If f(x) = 2x + 3, what is f(1)?

Back

f(1) = 5

Front

What does it mean for a function to be linear?

Back

A linear function has a constant rate of change and can be represented by a straight line on a graph.

Front
