Use the x-intercepts of the parabola and the given point to write a quadratic function in factored form.

The quadratic function in factored form is f(x)= __

answer: 1+1

step-by-step explanation: 1+1 is at least 2

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
