Lesson 3a – Introduction to Exponential Functions Practice Problems 3. For the following three exponential functions, identify the initial value (a), calculate the base (b) and then write the equation for the function. a) x f(x) 0 4 1 8 2 16 b) g = {(0, 2), (1, 4.2), (2, 5.88)} c) 4 -4 4 p(x) 4. Determine if each data set is linear or exponential, and write the formula for each. a) x -2 -1 0 1 2 3 4 f(x) .04 .2 1 5 25 125 625 b) x -2 -1 0 1 2 3 4 f(x) -1.375 -.5 .375 1.25 2.125 3 3.875 c) x -2 -1 0 1 2 3 4 f(x) -3 -5.5 -8 -10.5 -13 -15.5 -18 d) x -2 -1 0 1 2 3 4 f(x) 98.224 99.108 100 100.9 101.81 102.72 103.65 Scottsdale Community College Page 114 Intermediate Algebra
Lesson 3a – Introduction to Exponential Functions Practice Problems 5. In this problem, we look at the characteristics of exponential functions in more depth. For the following three equations, identify each of the characteristics. Initial Value (a)? f(x) = 3.4(1.13) x g(x) = 42(0.62) x h(x) = 1000(1.03) x Base (b)? Domain? Range? X-intercept? Y-intercept? Horizontal Asymptote? Increasing or Decreasing? 6. Given f(x) = 50(1.25) x solve each of the following a) f(5) = b) f(50) = c) find x when f(x) = 75 d) find x when f(x) = -25 7. Given f(x) = 100(0.90) x solve each of the following a) f(3) = b) f(30)= c) find x when f(x) = 25 d) find x when f(x) = 50 Scottsdale Community College Page 115 Intermediate Algebra
