The graph models the decay of a sample of iodine-125, where x is the time that has passed and y is the amount remaining in the sample in grams. what was the size of the sample at the beginning of the experiment?

12.5 grams

25 grams

50 grams

120 grams

(f - g)(x) = 5x^3 - 3

step-by-step explanation:

rearrange these functions vertically, with like terms in separate columns:

f(x) = 5x^3 - 2

g(x) =         +1

now subtract, column by column:

(f - g)(x) = 5x^3 - 3
