Asimple exponential has the form y =bx explain how to determine what the graph would look like

You mean y = b^x.

By plugging different values of x, we find different y-values forming points in the form (x, y).

After 2 or 3 points, we can clearly see that the graph of y = b^x passes through the point (0, 1) and extends forever in the upward direction through quadrant 1.

X= 2 he can buy 2 packs of cards for $12 and an action figure for $3 so he would spend $15 in total plus the free poster
