Example 21 Content Objective: Precalculus/Functions/Graph and Identify Domains, Ranges, Intercepts, and Zeros of Exponential Functions The amount in grams of a radioactive substance remaining after t years is given by the function A(t)=A0eh−ln2, where A0 represents the initial amount in grams and h represents the half-life in years. Which change in the half-life or initial amount of a substance would horizontally stretch the line of the graph by a factor of 2 on the vertical axis as a function of time on the horizontal axis? A. Doubling the initial amount B. Doubling the half-life C. Halving the initial amount D. Halving the half-life
