The table shows the outputs y for different inputs x:
2 4 6 8
1 2 3 4
Part A: Do the data in this table represent a function? Justify your answer. (3 points)
Part B: Compare the data in the table with the relation f(x) = 3x – 10. Which relation has a greater value when x = 8? (2 points)
Part C: Using the relation in Part B, what is the value of x if f(x) = 80? (5 points)

Ok so what makes something a function?
@DJJo Idk that's why I am asking please help
yes it represents a function as long as there is an x and y value it does (x,y)

Ok, so what makes this a function is that there is one domain for each range and there can only be one domain per range like this:
and you can't have a domain who has 2 ranges:
does that make sense?
OK thank you but can you help me with awnsering Part A and PArt B and Part c???
ok so now with the function they gave you f(x) = 3x - 10
you replace x with 8 so f(x) = 3(8) -10
what does that equal?
