Review - Points, Functions, & Function Notation

Front

What is an ordered pair?

Back

An ordered pair is a pair of numbers used to represent a point in a two-dimensional space, written in the form (x, y), where x is the horizontal coordinate and y is the vertical coordinate.

Front

What does the domain of a function represent?

Back

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

Front

What does the range of a function represent?

Back

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

Front

How do you identify the x-coordinate in an ordered pair?

Back

In an ordered pair (x, y), the x-coordinate is the first number, which indicates the horizontal position on the graph.

Front

How do you identify the y-coordinate in an ordered pair?

Back

In an ordered pair (x, y), the y-coordinate is the second number, which indicates the vertical position on the graph.

Front

What is function notation?

Back

Function notation is a way to represent a function using symbols, typically written as f(x), where f represents the function and x is the input value.

Front

What is the significance of the point (0, 0) in a coordinate plane?

Back

The point (0, 0) is known as the origin, where the x-axis and y-axis intersect.

Front

How can you determine if a point lies on a function's graph?

Back

To determine if a point (x, y) lies on a function's graph, substitute the x-value into the function and see if the output equals the y-value.

Front

What is the difference between discrete and continuous functions?

Back

Discrete functions consist of distinct, separate values, while continuous functions can take any value within a given range.

Front

What is the vertical line test?

Back

The vertical line test is a method used to determine if a graph represents a function; if a vertical line intersects the graph at more than one point, it is not a function.
