Algebra 1 Functions Test

Front

What is a function?

Back

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

Front

What is the vertical line test?

Back

The vertical line test is a method to determine if a curve is a function. If a vertical line intersects the curve at more than one point, it is not a function.

Front

How do you find the value of a function at a specific point?

Back

To find the value of a function at a specific point, substitute the x-value into the function's equation and solve for y.

Front

What is the zero of a function?

Back

The zero of a function is the x-value where the function's output (y-value) is zero.

Front

What is the domain of a function?

Back

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

Front

What is the range of a function?

Back

The range of a function is the set of all possible output values (y-values) that the function can produce.

Front

What does it mean for a function to be linear?

Back

Front

How do you determine if a set of points represents a function?

Back

A set of points represents a function if no two points have the same x-value with different y-values.

Front

What is an ordered pair in the context of functions?

Back

An ordered pair is a pair of numbers (x, y) that represents a point on the Cartesian plane, where x is the input and y is the output.

Front

What is a slope in a linear function?

Back

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