Answer:
What are the options?
Step-by-step explanation:
Answer:
b is not a function
Step-by-step explanation:
To be a function there must be a one to one correspondence.
Each x must only go to one y
b has an x that goes to two different y's
1 goes to 5 and 13. That makes it a relation not a function
80
8 x 10
2 x 4 x 5 x 2
2 x 2 x 2 x 2 x 5 <===
Answer:
The set of natural numbers can be denoted as: {} (null set) because no natural number will satisfy the given equation.
Step-by-step explanation:
Given equation:

To find the set of natural numbers that satisfies the above equation.
Solution:
In order to find the set of solutions for the equation, we will solve it for 
We have:

Subtracting both sides by 8.

∴ 
Thus, we get only one solution for
that satisfies the given equation but it is not a natural number. -3 is an integer.
Set of natural numbers {1,2,3,4,5,6........}
Thus, we can say the set of natural numbers that satisfies the equation is a null set {}.
I believe it is C but i can’t be sure but I hope u get it right!
