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. Which of the following is not true about function?

a. Function is composed of two quantities where one depends on the other.

b. One-to-one correspondence is a function.

c. Many-to-one correspondence is a function.

d. One-to-many correspondence is a function.

2. In a relation, what do you call the y values or the output?

a. Piecewise

b. Range

c. Domain

d. Independent

We 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 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 Practice 2 1. A tricycle ride costs P10.00 for the first 2 kilometers, and each additional kilometer adds P8.00 to the fare. Use a piecewise function to represent the tricycle fare in terms of the distance d in kilometers. Answer: 10 if. c(d)= ( )ifd>3 (Fill in the missing terms to show the piecewise function of the problem) 3. A parking fee at SM Lucena costs P25.00 for the first two hours and an extra P5.00 for each hour of extension. If you park for more than twelve hours, you instead pay a flat rate of P100.00. Represent your parking fee using the function p(t) where tis the number of hours you parked in the mall. Answer: 25 if p(t) = (25 + 5t) if (Fill in the missing terms to show the ift >12 piecewise function of the problem)3. Which of the following tables is NOT a representation of functions? X 2 0 y 3 6 2 b. X -2 - 1 y -3 0 3 C. X -1 -2 -3 -4 y 1 2 3 4 d. X 0 2 4 6 y 6 5 4 3 4. In this table, what is the domain of the function? X 2 4 5 y a b C d e a. D: (2, 4, 6, 8, 10) b. D: (a, b, c, d, e) C. D: (1, 2, 3, 4, 5) d. y = (1, 2, 3, 4, 5, a, b, c, d)
