    If the y was an x, do you know what the graph would look like?

    Let's identify what we know. Is 2^y ever negative? Is it ever 0?

    What happens as y gets larger? What happens when y is negative?

    if it's negative the graph goes down i think and the exponent determines which way it goes,

    With a larger and larger negative exponent, it gets closer and closer to 0. With a larger and larger positive exponent, it gets larger and larger. So, we're looking for the graph that never results in a negative x value. It gets closer to 0 with the larger negative y, and gets further and further from the y axis as y gets larger. Which of the graphs follows this pattern?

    I eliminated B and c because they look they're getting close to zero and D is increasing in y value but to the negative so i think the answer is "A"

    A goes into the negative x values, so it can't be A. So does D.

    Is B increasing in y value the most?

    I'm not sure what you mean by that. We're looking for the graph of the equation: 2^y We know what this will do in certain situations (such as it will never go negative). This means we can eliminate graphs A and D, as the line shown on there goes into negative X values.

    After that, we can look at 2^1 = 2 and 2^0 = 1 to eliminate one of the other two graphs.

    why did you have them to the ^1 and ^0

    Those are the results when y = 1 and y = 0. We can see which graph of the remaining two goes through the correct points. y = 0: 2^0 = 1 So we look for the point where x=1 and y=0, and see if the graph goes through that point.
