Study Notes
Logarithmic and Exponential Functions
Representing Logarithmic Functions
- A logarithmic function can be represented as f(x) = loga(x) where 'a' is the base and 'x' is the argument
- The graph of a logarithmic function has a vertical asymptote at x = 0
- Logarithmic functions can be used to model real-world scenarios, such as the pH level of a solution or the magnitude of an earthquake
Exponential Functions in Equivalent Forms
- Exponential functions can be expressed in equivalent forms to reveal properties of the graph, such as y = ab^x and y = Ae^(kx)
- The equivalent forms can help identify the initial value, growth rate, and asymptotes of the graph
- Exponential functions can be used to model population growth, radioactive decay, and chemical reactions
Constructing Exponential Functions with Natural Base
- An exponential function with natural base 'e' can be represented as f(x) = e^x or f(x) = Ae^(kx)
- The natural base 'e' is approximately equal to 2.718
- Exponential functions with natural base are used in modeling population growth, compound interest, and probability distributions
Solving Equations Involving Exponential and Logarithmic Functions
- Equations involving exponential functions can be solved by rewriting them in logarithmic form
- Equations involving logarithmic functions can be solved by rewriting them in exponential form
- Contextual scenarios, such as population growth and chemical reactions, can be modeled using exponential and logarithmic functions
Inverse Functions of Exponential and Logarithmic Functions
- The inverse function of an exponential function is a logarithmic function
- The inverse function of a logarithmic function is an exponential function
- Inverse functions can be used to solve equations and model real-world scenarios
This multiple-choice quiz assesses your understanding of constructing representations of logarithmic and exponential functions, expressing exponential functions in equivalent forms, using the natural base e, solving equations involving exponential or logarithmic functions, and constructing representations of inverse functions of exponential functions.
