Unit 5 Intro - Interpreting Inputs & Outputs

Front

What are coordinates?

Back

Coordinates are a set of values that show an exact position on a graph, usually represented as (x, y).

Front

What does the x-coordinate represent?

Back

The x-coordinate represents the horizontal position on a graph.

Front

What does the y-coordinate represent?

Back

The y-coordinate represents the vertical position on a graph.

Front

What is an ordered pair?

Back

An ordered pair is a pair of numbers used to locate a point on a graph, written in the form (x, y).

Front

How do you find the output of a function?

Back

To find the output of a function, substitute the input value into the function rule.

Front

What is a function rule?

Back

A function rule is a mathematical expression that describes the relationship between input and output.

Front

What is the output when the input is 14 for the function rule x - 5?

Back

The output is 9.

Front

What is the significance of the point (0, y) on a graph?

Back

The point (0, y) represents where the graph intersects the y-axis, known as the y-intercept.

Front

What is the significance of the point (x, 0) on a graph?

Back

The point (x, 0) represents where the graph intersects the x-axis, known as the x-intercept.

Front

How do you identify a point on a graph?

Back

To identify a point on a graph, locate the x-coordinate on the horizontal axis and the y-coordinate on the vertical axis.
