Alicia's Reflection #20 (Christmas Holiday)

Okay so my holidays went by super fast. We go back to school tomorrow already :( I going to reflect on some stuff from chapter 2.

Polynomials and function notation

degree: the highest exponent

0- constant
1- linear
2-quadratic
3-cubic
4-quartic
5-quintic

** No variable can be in the denominator for a polynomial

**A root, zero, and x-intercept are the same thing

**Polynomial- equation with only addition and subtraction of terms

**Leading term- term with highest degree

**Function notation f( ) = plug in what is in ( ) for x.

**Synthetic division- used to factor.

Ex.) x^9+5x^7+4x^10+9x^2+4

A.) Is the equation a polynomial? yes

B.) What is the degree? 10

C.) What is the leading term? 4x^10

D.) What is the leading coefficient? 4


Ex.) f(x) = x^3+5x^2+5x-2

A.) find f (2)= (2)^3 +4(2)^2+1
= 8+4(4)+1
=8+16+1
= 25


Hope everyone had a good holidays....See yall tomorrow!
