Which of the following relations represents a function?

a. {(1, 1), (1, 2), (1, 3)}
b. {(1, 1), (2, 1), (3, 1)}
c. {(1, 1), (2, 2), (3, 3)}
d. both b and c.

Alternative D is correct

Step-by-step explanation:

For a relation to qualify as a function, a unique x value should be mapped to a unique y-value or unique x-values be mapped to the same y-value

answer:   14

step-by-step explanation:          

pu you stank bo u ugly bo lol

set each factor equal to 0

4x-3 = 0

2x-1 = 0

solve for x.

4x-3=0

4x=3

x= 3/4

solve for x. 

2x-1= 0

2x= 1

x= 1/2

eventually after a few more steps, your answer should be 1/2 is less than or equal to x and 3/4 is greater than or equal to x
