Question

Which out of these 2 "graphs" represent a proportional relationship? PLEASE HELP

x f(x)
–1 –2
0 0
1 2
4 8




x f(x)
–2 2
0 4
2 6
3 7

Answer 1

I believe the second option, (-2.2)-(3,7), is proportional because it increases up one over one everytime if you draw it. 

Answer 2

the bottom one since as x increases so does y. the top function doesn't since it's a quadratic. meaning it decreases and hen increases
