Answer 2

how far did you get?

Answer 3

Er...No where? Does f equal y?

Answer 4

yes, y = f(x)

Answer 5

plug in x to get y or f(x)

Answer 6

let's say you plug in x = 2

f(x) = 5^x

f(2) = 5^2

f(2) = 25

so when x = 2, y is y = 25. The point is really (2,25) and NOT (2,10)

Answer 7

OK. I think I get it. I think they're suppose to be more than one answer though.

Answer 17

I'm just guessing. I see how the first one makes sense but not the others.
