We used the equation y=3^-x and tried to graph the points on paper by first filling out a data table and then raising the Y axis number on the graph by 15 each time. When X was positive, Y was less than 1, and when X was negative, Y was much greater than one. The distances between the points increased quite rapidly, so it was difficult to graph the numbers, as there was a big difference between each. This activity helped me to see the relationship between the positive and negative exponents.

When compared, we noticed that group #5’s graph is the exact opposite of ours, as theirs is positive (y=3^x) and ours is negative (y=3^-x). The graph was flipped on the y axis, but other than that, all the numbers on the Y axis were the same (just in different/opposite order).
