It is customary to symbolize a function using letters from the Latin alphabet when the two most common notations are:
(Of course, similar notations can also be used).
The - inside parentheses expresses that it is an independent variable of the function and the function's dependency ( or ) on it. ,,
Determine whether the data in the following table represent a constant function
In the blog of Tutorela you will find a variety of articles with interesting explanations about mathematics
Determine whether the data in the following table represent a constant function
It should be remembered that a constant function describes a situation where as the X value increases, the function value (Y) remains constant.
In the table, we can see that there is a constant change in X values, meaning an increase of 1, and a non-constant change in Y values - sometimes increasing by 1 and sometimes by 4
Therefore, according to the rule, the table does not describe a function
No
Determine whether the following table represents a function
It is important to remember that a constant function describes a situation where as the X value increases, the function value (Y) remains constant.
In the table, we can see that there is a constant change in X values, meaning an increase of 1, and a constant change in Y values, meaning an increase of 3
Therefore, according to the rule, the table describes a function.
Yes
Determine whether the following table represents a function
It is important to remember that a constant function describes a situation where as the X value increases, the function value (Y) remains constant.
In the table, we can see that there is a constant change in the X values, specifically an increase of 2, and the Y value remains constant.
Therefore, according to the rule, the table describes a constant function.
Yes
Does the graph below represent a function?
It is important to remember that a function is an equation that assigns to each value in domain only one value in range .
Since we can see that for every value found on the graph there is only one corresponding value, the graph is indeed a function.
Yes
Is the given graph a function?
It is important to remember that a function is an equation that assigns to each element in domain X one and only one element in range Y
We should note that for every X value found on the graph, there is one and only one corresponding Y value.
Therefore, the graph is indeed a function.
