The function y=10x+100 represents the amount y (in dollars) of money in your bank account after you babysit for x hours. a. Identify the independent and dependent variables.

The dependent variable is the amount of money in the bank account.

The independent variable is the hours you babysit.

Question 2
b. You babysit for 4 hours. Find the domain and range of the function.

domain:

range:

Domain - [0, 4]

Range - [100, 400]

Step-by-step explanation:

Function representing the amount of money 'y' and hours of babysitting 'x' is,

y = 10x + 100

a). The dependent variable is,

   Amount of money in the bank account.

    The independent variable is,

   Number of hours of babysitting

b). x       0        1         2         3        4

    y      100    110      120     130     140

   Since, x values of a function represent the domain and y-values represent the range,

   Domain - [0, 4]

   Range - [100, 140]
