Evaluate f(x - 2) when f(x) = 4x² - 4x – 2

b is the answer that makes most sense

step-by-step explanation:

the answer to this is a. a^2 + b^2 = c^2

where is the graph

step-by-step explanation:

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
