Which function has the same range as f(x)=-2/x-3+8?
g(x)= x-3-8
g(x)= x-3+ 8
g(x)=-x+3 +8
g(x)=-1/x-3-8

step-by-step explanation:

hopefully im right

ending amount = beginning amount / (2^n)

where "n" = number of half-lives (or elapsed time / half-life)

ending amount = 50 mg / (2 ^10 / 5.3)

ending amount = 50 mg / (2 ^ 1.8867924528)

ending amount = 50 m / 3.6981210597

ending amount = 13.5203794557 mg

or about 13.5 mg remain
