A) the quadratic at y=3.5 is well above the exponential
B) the most likely choice (3.5, 17)
C) at x=-8, the quadratic is above the exponential
D) neither graph goes anywhere near y = -8
3 times the product of 5 and b is reduced by 2
3*(5*b)-2
15b-2
The Formula:Number of stacks multiplied by number of pennies in each stack
