Answer: Number 7 is not a function. Also number 8 is not a function.
Step-by-step explanation:
Number 7s x and y values in the table do not increase or decrese at a constant rate so the table is not a function.
Number 8_ So the x input 6 has two y outputs so that makes it not a function. In other words an input or x value only has 1 and only 1 output to make it a function.
I hope this helps! I could only answer the question about the functions on numbers 7 and 8 not the Domain and range for those questions.
