In this section, we will review some of the main topics and features of the textbook. We will also provide some examples and questions from the textbook to illustrate the content and style of the textbook.
Linear and Quadratic Functions
The first chapter of the textbook introduces the concept of functions and how to represent them using different forms, such as equations, tables, graphs, and function notation. The chapter also explains how to identify the domain and range of functions, and how to determine the number of zeros and the maximum or minimum value of a quadratic function. The chapter also explores how to transform quadratic functions and how to solve problems involving the intersection of a linear and a quadratic function.
For example, one of the questions in the chapter asks students to find the equation of a quadratic function that has the same zeros as f(x) = x^2 - 5x - 6 and passes through the point (2, 5). The solution is as follows:
Since f(x) has the same zeros as the given function, we can write f(x) = a(x + 1)(x - 6), where a is a constant.
To find the value of a, we can substitute x = 2 and f(x) = 5 into the equation and solve for a.
f(2) = a(2 + 1)(2 - 6) = 5
a(-4)(3) = 5
a = -5/12
Therefore, f(x) = -5/12(x + 1)(x - 6)
We can expand this expression to get f(x) = -5/12x^2 + 25/6x + 5/2
This question demonstrates how to use function notation, factoring, substitution, and algebraic manipulation to find the equation of a quadratic function given some information about it.
Exponential and Logarithmic Functions
The second chapter of the textbook covers exponential and logarithmic functions and their properties. The chapter explains how to graph exponential and logarithmic functions using transformations and asymptotes. The chapter also shows how to solve exponential and logarithmic equations using equivalent forms, inverse operations, and common bases. The chapter also applies exponential and logarithmic functions to model real-world situations such as population growth, radioactive decay, pH levels, and sound intensity.
For example, one of the questions in the chapter asks students to determine how long it takes for a sample of uranium-238 to decay to half its original mass. The solution is as follows:
We can use the formula A = A_0e^(-kt) to model the decay of uranium-238, where A is the mass after t years, A_0 is the original mass, k is the decay constant, and e is the base of natural logarithms.
We can find the value of k by using the fact that uranium-238 has a half-life of 4.47 billion years. This means that A = A_0/2 when t = 4.47 billion.
A_0/2 = A_0e^(-k(4.47 billion))
Dividing both sides by A_0 and taking natural logarithms of both sides, we get ln(1/2) = -k(4.47 billion)
Solving for k, we get k = -ln(1/2)/(4.47 billion)
k â 1.55 x 10^-10
Therefore, A = A_0e^(-1.55 x 10^-10t)
To find how long it takes for A to be half of A_0, we can set A = A_0/2 again and solve for t.
A_0/2 = A_0e^(-1.55 x 10^-10t)
Dividing both sides by A_0 and taking natural logarithms of both sides, we get ln(1/2) = -1.55 x 10^-10t
Solving for t, we get t = -ln(1/2)/(1.55 x 10^-10)
t â 4.47 billion
