Exponential Function

Module 23 Study Stack Projet

27^x+1=9 x=-1/3
625^x=3125 x=5/4
3^x=9 x=2
16^x=8 x=3/4
One type of uranium has a daily radioactive decay rate of 0.4%. If 30 pounds of this uranium is available today, find out how much will still remain after 50 days? Use y=30(0.996)^x and let x be 50 days. The quantity left after 50 days is 24.6 pounds of uranium
Is y=2^x an exponential growth or decay? Exponential Growth
Is y=(1/2)^x an exponential growth or decay? Exponential Decay
Is this an exponential growth of decay function? y=a(1-r)^t? Exponential Decay due to the subtraction sign.
