Isotope X has a half-life of 45 minutes. If you start with 853 g of the isotope, then how
many grams will you have after 700 minutes?

Which of the following pairs of functions are inverses of each other? o a. f(x)=x72+8 and 96-9 = 7/x+2) =8 o b. f(x)= 6(x - 2)+3 and g(x) - *#2-3 o c. $4) = 5(2)-3 and 90- 4*: 73 o d. f(x) = 6)-12 and 910 – +12

F(x)= 4x g(x) =x-1 what is f(x) divided by g(x)
