Answer 5

ok the graph, X has to be equal to or over 0 correct?

Answer 6

no, x can be all +ve or negative numbers

Answer 7

y values (output / range) is stuck in the +ve range tho...

Answer 8

Yah, our x is going all the way right and left.
It's going up much faster than it's moving right or left, that might make it a lil confusing. But we WILL cover all the x's.
