A table, graph, or equation represents a function if each input (or x-value) has exactly one output (or y-value). For a table, check that no x-value repeats with different y-values. In a graph, a vertical line drawn through any x-value should intersect the curve at most once. For an equation, it must pass the vertical line test when graphed, meaning it can be expressed in a form where every x-value corresponds to only one y-value.

Explain how you can use a table of values and equation and a graph to determine whether a function represents a proportional relationship?
To determine if a function represents a proportional relationship, you can use a table of values to check if the ratio of the output (y) to the input (x) remains constant. If the ratios are consistent, the relationship is proportional. Additionally, graphing the function will help you visualize the relationship; if the graph is a straight line that passes through the origin (0,0), then the function is proportional. If either the table or graph does not meet these criteria, the relationship is not proportional.
Consider the equation below. Complete the table of values for the equation. Then determine whether the equation represents a function. x y -26 -1 9?
To determine if the equation represents a function, we need to see if each input ( x ) has a unique output ( y ). In the provided table, there are three values for ( x ): -26, -1, and 9. If each ( x ) corresponds to a single ( y ), then the equation represents a function. However, without knowing the specific relationship or equation that relates ( x ) and ( y ), we can't definitively complete the table or confirm the nature of the relationship.
What are 3 different methods that can graph a linear equation?
You could put the equation in slope-intercept form or in parent linear function or even make a table of values.
How can you tell whether a table of values represents function?
A table of values represents a function if each input (or x-value) corresponds to exactly one output (or y-value). To check this, look for repeated x-values in the table; if any x-value appears more than once with different y-values, it does not represent a function. Additionally, you can use the vertical line test: if a vertical line drawn through the graph of the points intersects the graph at more than one point, it is not a function.
How do you graph an equation in the table of values?
Which of the following is a disadvantage to using equations?

How can you determine that a set of ordered pairs are a graph table diagram equation a function or mere relation?
In general you cannot. Any set of ordered pairs can be a graph, a table, a diagram or relation. Any set of ordered pairs that is one-to-one or many-to-one can be an equation, function.
What are 4 ways to represent a function?
Input/output table, description in words, Equation, or some type of graph
