C. ASSESSMENTIAPPLICATION Direction: Read each question carefully. Write the letter which corresponds to the correct answer on The space before each number.
1. Does the given mapping diagram on the right define a function? Why or a why not? A. Yes, because the x-value 11 has two y-values mapped to it. B. Yes, because each x-value has only one y-value mapped to it. C. No, because the x-value 11 has two y-values mapped to it. D. No, because each x-value has only one y-value mapped to it. +15 11 18
2. Which of the following set of ordered pairs DOES NOT define a function? A. {(4,0),(4,1),(4,2)} B. {(0,-2); (1,1),(3,7), (2,4)} C. {(-2,2), (-1,1),(0,0)} D. {(3,3), (0,0), (-3,3)}
3. Which of the following graphs define a function? A у B. ►x х C. АУ у D. Х
4.The following rules define a function except for one. What is it? A. y = 3x + 5 B. y=x2 C. y2 = 2x + 3 D. y = x2 + 10
5. Which statement is/are true about functions? A. A function is a relation. B. Some relations are not functions. C. Only one-to-one correspondence and many-to-one correspondence are functions. D. all of the above х y 12 ܝܕ ܬ -3
6. Based on the mapping diagram on the right, is the relation a function? Why or why not? A. Yes, because each x-value has two y-values mapped to it. B. Yes, because each x-value has only one y-value mapped to it. C. No, because each x-value has two y-values mapped to it. D. No, because each x-value has only one y-value mapped to it.
7. Which of the following set of ordered pairs DOES NOT define a function? A. {(2,3), (4,5).(-2,-1),(0,1)} B. {(2,6), (3,6), (4,6), (5,6)} C. {(3,0), (5,1), (7,2), (3,3)} D. {(3,0), (0,3), (4,8), (8,4)} 8 6 -6
