Answer:

HOPE IT HELPS PLZ MARK ME BRAINLIEST

Step-by-step explanation:

A={1,2,3,4,5,6}

R={(x,y):y is divisible by x}

We know that any number (x) is divisible by itself.

(x,x)∈R

∴R is reflexive.

Now,(2,4)∈R [as 4 is divisible by 2]

But,(4,2)∈ /

R. [as 2 is not divisible by 4]

∴R is not symmetric.

Let (x,y),(y,z)∈R. Then, y is divisible by x and z is divisible by y.

∴z is divisible by x.

⇒(x,z)∈R

∴R is transitive.

Hence, R is reflexive and transitive but not symmetric.

oksian1 [2.3K]

Answer: hi there! your answer should be d let me tell you why...

This function has no zeros.

This is because f(x)=12, meaning no matter the x value, the y value is always 12. If the y value is always 12, it is never 0, and therefore has no zeros.

hope this help have a great day! let me know if im right or wrong plz!:)
