Answer:
x+2
Step-by-step explanation:
i put mi x as one so
....that how i get my anwser
2 1/5: 11/5, 22/10, 33/15, 44/20 etc.
1 5/6: 11/6, 22/12, 33/18, 44/24, etc.
Quadratic is where the degree of x is 2
I would think 3 is the one that might have been written as y=x² which would be correct
They are not equivalent, try adding in numerical values for x, both do not come out the same.
