Hi! I’m super confused on the second page but for the first page I only need help on #11. Could you please let me know if the problems I did answer on the first page are correct?

Answer:

So ummmm..... I personally think that all of your answers on the first page should be flipped.

Second page:

#9: domain= [0,6] range=[-6,6]

#10: Domain= (-infinity, infinity) range: (-infinity, infinity)

#11: Domain= (-infinity, infinity) range: [-2, infinity)

Thats all I have time for

(Write infinity as the sideways 8)

A function is a relationship between input values and output values such that each input has exactly one output

The correct values are;

First page

11. A skateboarder motion

Second page

9. The square is not a function

10. Domain; -∞ < x < ∞

Range; -∞ < x < ∞

11. Domain of the graph is; -∞ < x < ∞

Range is; 2 ≤ y < ∞

12. A circle is not a function

13. Domain is; -∞ < x < ∞

Range; -2 ≤ y ≤ 4

14. Domain; -∞ < x < ∞

Range; y = 2

15. The relationship is a function

16. The relationship is not a function

17. The relationship is not a function

18.The given relationship is not a function

19. The relationship is a function

20. The relationship is not a function

21. The relationship is a function

22. The relationship is not a function

Reason:

First page;

11. The given graph can be described by the following real life situation;

Second page;

The domain and range of a

The domain of a function is set values of the input to the function where the function is defined

The range of a function are is the set of the output values of the function

9. The given figure of a square is not a function

10. The graph extends to infinity towards the top right, and the bottom left

11. The graph of the function extends infinity at the top left and top right

The graph has a minimum at y = 2, while it extends to infinity as the y-values increases, therefore;

12. The graph of a circle is not a function

13. The end behavior of the graph is as follows;

The graph is repeating and extending to infinity at the left and right ends

Therefore;

The maximum y-value is y = 4, the minimum y-value is y = -2, therefore;

14. The graph of the function is an horizontal line, y = 1, extending to infinity to the left and right, therefore;

Therefore;

15. The given data are; {(-2, 6), (2, 0), (3, 0), (4, -1), (5, 3)}

The relationship is a function

16. The given data values are presented as follows;

{(-3, 2), (-2, 2), (1, 2), (-3, 1), (0, 3)}

The relationship is not a function

17. The given data are presented as follows;

[tex]\begin{array}{|c|cc|}\mathbf{x}&&\mathbf{y}\\-2&&-3\\-1&&0\\5&&5\\4&&3\\-1&&7\end{array}\right][/tex]

The x-value, -1, has two different outputs, 0, and 7, therefore, the data is not a function

The relationship is not a function

18. In the given data, the x-value, 6, has two y-values, 3 and 5, therefore, the given relationship is not a function

19. The given graph is a function because each vertical line drawn from the horizontal axis, crosses the data points only once

The relationship is a function

20. The given graph is not a function because each vertical line crosses the graph only once

The relationship is not a function

21. The graph of is a function because each vertical line drawn from the horizontal axis crosses the graph at one point only

The relationship is a function

22. The graph is not a function because it has several points on the side that is vertical to the y-axis
