ByLogarithm (log). How do we know that 10 log 10 1000 = 10 x 3 ? Logarithmic and Exponential Functions Logarithmic and exponential functions are inverses of each other: If y = log b x then x = b y In words, log b x is the exponent you put on base b to get x . lol So,

ByExponential Functions, Growth and Decay. 4-1. Warm Up. Lesson Presentation. Lesson Quiz. Holt McDougal Algebra 2. Holt Algebra 2. Warm Up Evaluate. 1. 100(1.08) 20 2. 100(0.95) 25 3. 100(1 – 0.02) 10 4. 100(1 + 0.08) –10. ≈ 466.1. ≈ 27.74. ≈ 81.71. ≈ 46.32. Objective.

ByExponential Functions are functions which can be represented by graphs similar to the graph on the right. All base exponential functions are similar because they all go through the point (0,1), regardless of the size of their base number. Exponential Functions are written in the form: y = ab x

By3.2 Inverse Functions and Logarithms. 3.3 Derivatives of Logarithmic and Exponential functions. One-to-one functions. Definition: A function f is called a one-to-one function if it never takes on the same value twice; that is f(x 1 ) ≠ f(x 2 ) whenever x 1 ≠ x 2 .

ByReal-Valued Functions of a Real Variable and Their Graphs. Lecture 43 Section 9.1 Wed, Apr 18, 2007. Functions. We will consider real-valued functions that are of interest in studying the efficiency of algorithms. Power functions Logarithmic functions Exponential functions.
