Exponential Growth & Decay Project

Use the growth or decay factor I assign you and draw the results of using x = -3, -2, -1, 0, 1, 2, 3, 4. (That is 8 different depictions.) Neatness counts!!!! Add color; keep the same shape and size the entire time. You can choose an “a” value other than one for bonus points. Work out the problem for each of the x values.
