 what is the answer for this question does this table represent a function? why or why not? hours of training 10,20,30,40,50,60,70, and monthly pay 1220,1420,1620,1820,2020,2220,and 2420.

Respuesta :

The domain values uniquely map to the dependent variable.
A function that fits these values is f(x)=20x+1020.

Answer: Yes, table represents a function.

Step-by-step explanation:

We know that a function is said to be a relation if for every independent variable corresponds to one unique dependent variable.

Given table :

Hours of training : 10 ,        20,     30,       40,       50,       60,       70

Monthly pay     : 1220,   1420,  1620,   1820,    2020,   2220,   2420.

Here the input variable is "Hours of training" and dependent variable is " Monthly pay " .

We can see that only one dependent variable corresponds to each independent variable.

Thus , we can say that the table represents a function.
