Estimate the half-life of the radioactive substance shown in the graph:

• 6 months

• 6 hours

• 1 year

• 1 minute

The half-life of ibuprofen is 1-hour. You take 400 mg of ibuprofen. Write an exponential equation that could be used to find the amount of ibuprofen you have remaining in your body after x hours.

• $y=400\left(\frac{1}{2}\right)^x$

• $y=400\left(2\right)^x$

• $y=400-2^x$

• $y=400-\left(\frac{1}{2}\right)^x$
