Exponential functions exhibit exponential growth (or decay). What does this mean to the graphs of these functions?a.the graph will rise or fall more dramatically than a polynomial graphc.the graphs represent the population of bacteria in your mouthb.the graph is three dimensionald.the exponent in the equation is less than one

A guest on a talk show tends to receive many phone calls right after she is on the show, and then the calls become less frequent. This can be represented by the equation y = 30(0.92)d, where y is the number of phone calls after d days. How many phone calls should she expect after a week?a.28c.17b.23d.2
