Problem
Let . a. (a) Find the exact value of . b. (b) Evaluate . c. (c) Calculate the percentage decrease when changes from to . Give your answer correct to the nearest integer.Intuitive explanation
This is an exponential function where the base is greater than 1, so the function grows as increases. The key insight is recognizing that follows the form , where 7 is the initial value and controls how fast it grows—each unit increase in multiplies the output by . Understanding this structure lets you evaluate at any input, find growth rates, or solve equations involving exponential relationships.
