Arumor that was told initially to three people is spreading at a rate of 5% each week. the following function represents the weekly spread of the rumor: f(x) = 3(1.05)x. rewrite the function to show how quickly the rumor spreads each day and calculate this rate as a percentage.
a) f(x) = 3(1.007)7x; spreads at a rate of approximately 0.7% daily
b) f(x) = 3(1.05)7x; spreads at a rate of approximately 0.5% daily
c) f(x) = 3(0.15)x; spreads at a rate of approximately 0.15% daily
d) f(x) = 3(1.007)x; spreads at a rate of approximately 0.07% daily
