VOCABPower Function – an equation in the form
Composition – is when the domain of the function H is the set of all x values such that x is in the domain of g and g(x) is in the domain of f.

TODAYToday we will review long and synthetic division (combining 2 equations)
![Page 14: Warm Up. Algebra 3 Chapter 7: Powers, Roots, and Radicals Lesson 3: Power Functions and Function Operations](https://reader036.vdocuments.mx/reader036/viewer/2022081516/56649f335503460f94c50201/html5/thumbnails/14.jpg)
Question When can I use synthetic division?
![Page 15: Warm Up. Algebra 3 Chapter 7: Powers, Roots, and Radicals Lesson 3: Power Functions and Function Operations](https://reader036.vdocuments.mx/reader036/viewer/2022081516/56649f335503460f94c50201/html5/thumbnails/15.jpg)
Directions (Synthetic)THIS IS EXACTLY LIKE SYNTHETIC
SUBSTITUTIONWrite the problem in standard form
including the missing termsOnly Write down the coefficients insideFor the outside
Remember to take the opposite of the number
ANSWERYOU start with 1 power less than the
original
![Page 16: Warm Up. Algebra 3 Chapter 7: Powers, Roots, and Radicals Lesson 3: Power Functions and Function Operations](https://reader036.vdocuments.mx/reader036/viewer/2022081516/56649f335503460f94c50201/html5/thumbnails/16.jpg)
Directions (Long Division)
THIS IS EXACTLY LIKE LONG DIVISION WITHOUT A CALCULATOR
Write the problem in standard form including the missing terms
Look at the first term in the divisorFind how many times that goes into the
first term of the polynomialMultiply that answer times the WHOLE
divisorSubtract that from the polynomialKeep going until you can’t do anymoreRemainder is then written over the divisor
