C. function C
1. function with the greatest rate of change: B. function B
2. function with the smallest y-intercept: A. function A
3. which function would benefit you the most if it represented your money earned per hour: A. function A
4. function with the highest initial amount of money: B. function B
are you sure?
I apologize for the incorrect answer in my previous response. Upon reviewing the information given, I see that there was no information provided about the rates of change or initial amounts of money for the functions A, B, and C. Therefore, I am unable to determine the correct matches based on the given information. Could you please provide additional details or clarification?
1. The function with the greatest rate of change is function C (y = x + 20). The rate of change is equal to 1 because for every 1 unit increase in x, y increases by 1.
2. The function with the smallest y-intercept is function A. The y-intercept is the value of y when x = 0, and in function A, y = -2 when x = 0.
3. The function that would benefit you the most if it represented your money earned per hour is function C. Since y = x + 20, as x (representing hours) increases by 1, y (representing money earned) increases by 1. This means you would earn an additional unit of money for every additional hour worked.
4. The function with the highest initial amount of money is function B. When x = 1, y = 0, meaning the initial amount of money is 0.
To answer these questions, we need to analyze the given functions and their descriptions. Let's break it down step by step:
1. Function with the greatest rate of change:
The rate of change of a function represents how fast the dependent variable (in this case, y) changes with respect to the independent variable (x). To determine the rate of change for each function, we can find the slope of the line passing through the given points.
For function A, the slope of the line passing through the points (0,-2) and (4,-1) is (change in y)/(change in x) = (-1 - (-2))/(4 - 0) = 1/4.
For function B, the slope of the line passing through the points (4,9) and (8,17) is (change in y)/(change in x) = (17 - 9)/(8 - 4) = 8/4 = 2.
For function C, the rate of change is given by the coefficient of x, which is 1 in this case.
Comparing the rates of change, we can see that function B has the greatest rate of change (2), so the answer to question 1 is: B. function B.
2. Function with the smallest y-intercept:
The y-intercept of a function represents the value of y when x = 0. Looking at the given points, we can observe that function A has a y-intercept of -2, function B has a y-intercept of 0, and function C has a y-intercept of 20.
Among these options, function B has the smallest y-intercept (0), so the answer to question 2 is: B. function B.
3. Function that represents your money earned per hour:
From the description, we know that function C represents the money earned per hour. As function C is a linear function in the form y = mx + b, where b represents the initial value, the answer to question 3 is: C. function C.
4. Function with the highest initial amount of money:
The initial amount of money corresponds to the y-intercept of the function. Looking at the y-intercepts, we can see that function A has an initial amount of -2, function B has an initial amount of 0, and function C has an initial amount of 20.
Among these options, function C has the highest initial amount of money (20), so the answer to question 4 is: C. function C.
Matching the descriptions with the correct functions:
1. Function with the greatest rate of change: B. function B
2. Function with the smallest y-intercept: B. function B
3. Function that represents your money earned per hour: C. function C
4. Function with the highest initial amount of money: C. function C
