Mathematics I – Unit 1: Function Families . INTRODUCTION: In seventh and eighth grade, students learned about functions generally and about linear functions specifically. This unit explores properties of basic quadratic, cubic, absolute value, square root, and rational functions as well as new language and notation for talking about functions.

Find the cost of using 1.5 gigabytes of data, and the cost of using 4 gigabytes of data. To find the cost of using 1.5 gigabytes of data, C(1.5), we first look to see which piece of domain our input falls in. Since 1.5 is less than 2, we use the first formula, giving C(1.5) = \$25. The find the cost of using 4 gigabytes of data,

Satisfying properties (1) and (2) means that a pairing is a function with domain X. It is more common to see properties (1) and (2) written as a single statement: Every element of X is paired with exactly one element of Y. Functions which satisfy property (3) are said to be "onto Y" and are called surjections (or surjective functions).

These are the positive integers of the form 8 m, 8m, 8 m, where m ≤ 21 m \le 21 m ≤ 2 1 and gcd ⁡ (m, 21) = 1. \gcd(m,21)=1. g cd (m, 2 1) = 1. So the answer is ϕ (21) = (3 − 1) (7 − 1) = 12. \phi(21) = (3-1)(7-1) = 12. ϕ (2 1) = (3 − 1) (7 − 1) = 1 2. _\square Let n n n be a positive integer, then find

The inverse of an integer a under modulus n is an integer b such that a*b ≡ 1 mod n. An integer can have either one or no inverse. The inverse of a can be another integer or a itself. In the above table, we can see that 1 has an inverse, which is itself and 5 also has an inverse which is also itself. But 2, 3 and 4 do not have inverses.

Topic: inverse operations Functions and their Inverses 1.1 Inverse operations "undo" each other. For instance, addition and subtraction are inverse operations. So are multiplication and division. In mathematics, it is often convenient to undo several operations in order to solve for a variable. Solve for x, in the following problems.

The arctan function is the inverse of the tan function. One way of remembering what it looks like is to remember that the graph of the inverse of a function can be obtained by reflecting it through the straight line y = x. The two functions are shown in the figure below.
