The unit price is $0.20 because if 5 pencils is $1.00, you can divide the total price by the number of pencils to find the price of one pencil. 1/0.20 = 5
The example of exponential growth is: <span>c. y=0.5(1.5)x </span>
The function y = ab˟ is a can only be growth function if the value b>1. And if 0<b<1 it will decay. Therefore, the only correct value that fits the definition of exponential growth is option C.
