Example Question #23 : Linear, Quadratic, & Exponential Models*

An anti-diabetic drug, has a half-life of about  hours. If a patient was administered  of the drug at , how much is left at ?

Note: The half life formula is 

Possible Answers:

Correct answer:

Explanation:

This question is testing one's ability to recognize real life situations that have a exponential growth or decay over a certain interval and how to deal with them in function form.

For the purpose of Common Core Standards, recognize situations that have a exponential growth or decay over a certain interval, falls within the Cluster A of construct and compare linear, quadratic, and exponential model and solve problems concept (CCSS.Math.content.HSF.LE.A).

Knowing the standard and the concept for which it relates to, we can now do the step-by-step process to solve the problem in question.

Step 1: Identify the known values given in the question.

Step 2: Calculate .

Step 3: Substitute in known values into the half life formula to solve for .
