If u could show me how to solve these i would appreciate it

b. False

Step-by-step explanation:

First oval is a domain, second oval is a range.

To be a function, only one arrow should be from each number in domain,

but we have two arrows from number 6 and two arrows from the number 12. So, it is not a function.

false because,the x is repeating x.their are 2 arrows are pointing to the same number.

Step-by-step explanation:

how to tell if it is not a function

1)if x intercept is pointing to two numbers it is not a function

example:6 it is pointing at 2 and 4 so it would not be a function
