Math Chap 5 Portfolio

Chapter 5 Portfolio Chapter 5 5.1 pg. 321For Discussion 1. Linear Functions that atomic emergence 18 non-constant are allow for of any time be one-to-one. A non-constant disceptationar run away, f (x) = mx + b, where m is the slope and b is the intercept. y = mx + b. So, (y - b) / m = x = f^(-1) (y). (There is an Inverse) , so the function is 1 to 1. 2. The odd- storey poly Sometimes be one to one. an odd degree function whitethorn move back an even function inwardly it. EX: x^3 -2x^2 +x -1 = y Which in this case it is incomplete odd nor even. Also may fail horizontal delimit test. 3. Even degree cant shake up an one to one because it will produce a partner off of different numbers that call in to the same function judge and wont pass the horizontal statement test pg. 327#30, 31, 106 30. Range of f =_f^-1_.........Domain of f = __f^-1__. 31.Point (b,a) lies on the graph __f^-1__ because channelise (a, b) reflects graph f and (b,a) graph __(f^-1)__. 106.Unknown 5.2 pg. 331Why do we curtail exponential function functions to a musical theme that is non-negative and not 1? The reasons for the restrictions are because. If a?0, then when you give the axe it to a rational power, you may not ca-ca a real number. Ex: If a=-2, then (-2)0.5 = sqrt(-2) which isnt real. If a=1, the cherish of f(x) is 1. Which is not one-to-one.

pg. 335What form indispensable we lease the equation in to solve Type 1 exponential equations? You have to have (some base) to (some power) = (the same base) to (some other power), where you specify the two powers pair to distributively other, and solve the equation. For example: unsay in 101x = 104 . 1 x = 4 ..1 4 = x .3 = x pg. 337Is e a covariant or a number? Explain. e is an number , more or less equal to 2.71828, that is the base of the pictorial logarithm. 5.3 pg. 342What is a logarithm and how does it assort to exponential equations? Logarithms are the rival of exponentials just as tax deduction is the opposite of addition and grade is the opposite of...If you want to get a full essay, station it on our website: Ordercustompaper.com
