a. Does the table represent a function? Explain.
b. If possible, describe the function rule and complete the table.

(2,6)

step-by-step explanation:

cause i just did this and got the answer

you're welcome

a and c

for infinitely many solutions we require both left and right sides to be equal

distribute and simplify

a

14 - 8x = 20 - 8x - 6 = 14 - 8x ← both sides equal so infinite solutions

b

6x - 54 = 6x - 54 + x = 7x - 54 ← not equal

c

4x + 16 = 4x + 10 + 6 = 4x + 16 ← both sides equal so infinite solutions

d

5x - 40 + 10 = 5x + 10

5x - 30 = 5x + 10 ← not equal

the one where 1 and 2 are directly across from each other.
