FUNCTION

please help me reduce my workload

++ i'm very thankful if you can explain each of it

A. Choose the letter of the best answer.

1. What do you call a relation where each element in the domain is related to only

one value in the range by some rules?

a. Function c. Domain

b. Range d. Independent

2. Which of the following relations is/are function/s?

a. x = {(1,2), (3,4), (1,7), (5,1)}

b. g = {(3,2), (2,1), (8,2), (5,7)}

c. h = {(4,1), (2,3), (2, 6), (7, 2)}

d. y = {(2,9), (3,4), (9,2), (6,7)}

3. In a relation, what do you call the set of x values or the input?

a. Piecewise c. Domain

b. Range d. Dependent

4. What is the range of the function shown by the diagram? a. R: (3, 2, 1) b. R: (a, b) c. R: (3, 2, 1, a, b) d. R:(all real numbers) 2 5. Which of the following tables represent a function? a. X 0 1 1 0 y 4 5 6 7 b. X - 1 - 1 3 O y -3 3 X 2 -2 C. y -1 -2 -2 -1 X O -1 3 2 d. y 3 4 5 6We said that for a relation to become a function, the value of the domain must correspond to a single value of the range. Let's read some of the conversations and determine if they can be classified as function or not Scenario 1: June and Mae are in a long-time relationship until June realized that he wants to marry Mae. If I said yes, what We're together for the could you promise me? last 7 years and I believe you are my forever. Will you marry me? I love you too and I will marry you. I promise to love you forever, to be faithful and loyal to you until my last breath. Scenario 2: Kim is a naturally born Filipino but because of her eyes, many people confused if she is a Chinese. Let's see how she responds to her new classmates who are asking if she's a Chinese. Hey classmate, are No classmate! I was you a Chinese?" born Filipino and my parents were also pure Filipino. Haha, many have said that. But my veins run a pure Hey Kim, can you teach Filipino blood. me some Chinese language? I love Chinese, but I'm sorry I can't teach you because I am Filipino. I was born Filipino Kim, I thought you are and will die as a Chinese because of Filipino. your feature.Independent Prnetiee 2 1 . A. tricycle ride costs Pl D for the first 2 kilometers, and each additional kilometer adds PBDD to the fare. Use a piecewise function to represent the tricycle fare in terms of the distance d in kilometers.

A parking fee at SM Luoena costs PESHD for the first two hours and an extra FSDD for each hour of extension. If you park for more than twelve hours, you instead pay a flat rate of FIDDDD. Represent your parking fee using the function pIt] where t is the number of hours you parked in the mall.
