Math Chap 5 Portfolio

Chapter 5 Portfolio Chapter 5 5.1 pg. 321For Discussion 1. Linear Functions that argon non-constant are will of all time be maven-to-one. A non-constant disceptationar use of goods and services, 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-degree poly Sometimes be one to one. an odd degree function may withdraw an even function within it. EX: x^3 -2x^2 +x -1 = y Which in this case it is incomplete odd nor even. Also may tumble horizontal trace test. 3. Even degree cant break an one to one because it will produce a pair of contrasting numbers that return to the same function look upon and wont cash in ones chips the horizontal line 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 orient (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 floor that is non-negative and not 1? The reasons for the restrictions are because. If a?0, then when you get up it to a rational power, you may not get a real number. Ex: If a=-2, then (-2)0.5 = sqrt(-2) which isnt real. If a=1, the value of f(x) is 1. Which is not one-to-one.

pg. 335What form essential we have the equation in to solve Type 1 exponential equations? You have to have (some chemical group) to (some power) = (the same base) to (some other power), where you specify the two po wers pair to separately other, and solve t! he equation. For example: take in 101x = 104 . 1 x = 4 ..1 4 = x .3 = x pg. 337Is e a variable or a number? Explain. e is an number , approximately equal to 2.71828, that is the base of the natural logarithm. 5.3 pg. 342What is a logarithm and how does it relate to exponential equations? Logarithms are the opponent of exponentials just as subtraction is the opposite of assenting and division is the opposite of...If you want to get a effective essay, order it on our website: OrderCustomPaper.com
