Algebra 1 Unit 3 Test

Front

What is a function?

Back

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

Front

How can you determine if a relation is a function?

Back

Use the vertical line test: if a vertical line intersects the graph at more than one point, it is not a function.

Front

What are the zeros of a function?

Back

The zeros of a function are the x-values where the function equals zero (f(x) = 0).

Front

How do you find the range of a function?

Back

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

Front

What is the domain of a function?

Back

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