Okay, let me try this again-I meant 8, not 6-a typo but then why is y>=8 in this one and the other one it is y>-5 and not greater and equal-is it because of the positive sign? So for y = 3^x - 4, the range would be y >-4 and not y >= (-4), right-I'm just trying...

So is that the "K" I'm looking at to solve for the range-my teacher keeps talking about the a h, k, ect and what effect they have Like if it said y = 2^x + 8 the range would be y>6 Thank you
