3 13. Larry creates Function 1 is two linear functions of x. Function 1 is represented by the table below. Function 1 x y ody and Oren are each saving money to buy a new video game. The amount of money ody has saved at the end of each week is shown in the graph below. ody s Savings ccount Function 2 is described by the equation below. Function 2: y = 3x 1 Which statement about the functions is true? The y-intercept of function 1 is greater than the y-intercept of function 2. B. The value of function 1 is less than the value of function 2 for every value of x.. The rate of change of function 1 is greater than the rate of change of function 2.. The rate of change of function 1 varies, while the rate of change of function 2 remains constant. The amount of money, y, Oren has saved at the end of each week, x, can be determined by the equation below. y = 3.50x + 15 Which description correctly compares the amount of money ody has been saving to the amount of money Oren has been saving? ody started saving with more money than Oren, but Oren has been saving more money each week. B. ody started saving with more money than Oren, and he has been saving more money than Oren each week.. Both ody and Oren had the same amount of money saved when they started, but Oren has been saving more money each week than ody.. Both ody and Oren started saving with the same amount of money, but ody has been saving more money each week than Oren. page 3
