Exam 4
Unit 7
Applications of Polynomial Functions
Can be applied in real world situations
Polynomial Division and Rational Zeros Theorem
R.Z.T
Uses Synthetic to see real zeros
Synthetic Division
Faster but leaves more room for error if not careful
Long Division
Slow but Precise
Polynomial and Power Functions
Multiplicity
Determines how the line interacts with the zeros of the function
End Behavior
Depends on Sign and Power of the Function
Factoring Polynomials of Degree 3
Factoring Cubics
Rules depending on how the cubic function is
Unit 8
Application and Regression Modeling
Logarithmic Regression
Exponential Regression
Quadratic Regression
Linear Regression
Regression and Function Fitting
Data Trends
When K is close to 1, the stronger it is. If k is positive it has a positive correlation, but if negative then a negative correlation. The closer K is to zero means a weaker correlation.
Piecewise Functions
Line Jumps usually and can change rapidly
Direct and Inverse Variation
Variation Functions and Applications
