1) Reflections of functions f(x) over the x-axis or y-axis produce new equations by changing the sign of the y-values or x-values respectively.
2) The inverse of a function f(x) is denoted f^-1(x) and is found by switching the x and y values when graphed, effectively reflecting over the line y=x.
3) For example, the inverse of f(x)=2x+5 is found by graphing f^-1(x) which treats x as the output and y as the input.

Users are prompted to enter property details, mill rates, and other values for each corresponding section of the tax statement.
This document discusses statement and demand forms. Statement forms are used to provide information about an account, transaction, or balance. Demand forms are used to request payment for an amount owed, such as an invoice demanding payment for services or goods that have been delivered. Both statement and demand forms convey important financial information in different ways.
This document provides instructions for graphing circular functions over an interval from 0 to 2. It defines amplitude and period as key vocabulary terms and has students complete tables to graph sine, cosine, and tangent functions. It then asks students to complete a chart comparing the amplitude, period, domain, range, zeros, y-intercepts, and asymptotes of sine, cosine, and tangent functions.
Minor arcs on a circle are labeled with 2 letters and have a measure of less than 180 degrees. The document discusses properties of circles, triangles, and angles including: the Pythagorean theorem, that a radius will meet a tangent at 90 degrees, an inscribed angle is half the measure of the central angle if they share an arc, two inscribed angles subtended by the same arc are congruent, the interior angles of a triangle sum to 180 degrees, and the total measure of angles on a circle is 360 degrees.
Simple interest is calculated by multiplying the principal amount by the interest rate as a decimal and the time period in years. The principal remains the same and interest is paid at the end of each time interval. The formula is: Interest = Principal x Rate x Time. An example calculates the total repayment amount of borrowing $3,000 from the bank for 2 years at a 4% rate. Another example finds the principal amount if the interest paid after 6 months was $178.50 at a 10.5% annual interest rate. Exercises 1-15 provide additional practice calculating simple interest.
Budgeting involves planning spending based on earnings. People should save 10% of net pay and spend the rest on expenses, with no more than 30% of take-home pay going to housing costs. When preparing a budget, one determines monthly income and expenses, savings plans, and creates a monthly statement. Income sources include regular pay, bonuses, and benefits, while expenses are fixed costs like rent and variable costs like food and recreation. People should have a reserve of 2-3 months' pay for unexpected costs.
Local municipalities raise revenue through grants from other levels of government and property taxes. [1] Property taxes are based on the assessed value of a property as determined by an assessor. [2] The municipal government and school division collect taxes at rates based on the portioned assessment and total taxes needed divided by total property value. [3]
