Front

For the function (0,1), (1,-3), (2,-4), & (-4,1), which choice gives the correct domain & range?

Back

Front

What is a function?

Back

A function is a relation where each input has exactly one output.

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(0)?

Back

f(0) = 3

Front

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

Back

f(3) = 9
