1.2 EXPONENTIAL FUNCTIONS
Table of Function Graph of Function
Amount of drug in bloodstream after t hours when given 250 mg medication Q = f(t) = 250(0.6)t Exponential decay function
Solution: a, c, and p are positive and a = c < p (y-intercepts of each function) d and q are greater than 1 and q > d 0 < b < 1 The most frequently used base for an exponential function is the famous number e = 2.71828
Example 3: Convert the functions P = e0.5t and Q = 5e-0.2t into the form y = y0at . Solution:
Example 4: Convert the functions P = 3(1.05)t and Q = 5(.94)t into the form y = y0ekt .
