The function that shows how quickly the weeds grow each day is and the weed grows at a rate of approximately 3% daily
The standard form of an exponential function is given as y = ab^x
Given the exponential function that shows the rate at which the weed grew each day expressed as g(x) = 197(1. 25)^x
- x is the time in weeks
- Since<u> there are 7 days in a week,</u> the time will in the day will be expressed as 7x where x is in days.
Substitute x as 7x in the given exponential function to have:
If the growth rate was 25% each week, then;
0.25 = 7 days
x = 1 day
7x = 0.25
x = 0.25/7
x = 0.0357
Hence the weed grows at a rate of approximately 3% daily
