Lesson 25 - 9.2 # 1 Say if function is polynomial and to what degree: Yes is polynomial (variable to power) and degree 2.	Lesson 25 - 9.2 # 2 Say if function is polynomial and to what degree: Is not a polynomial (exponential).
Lesson 25 - 9.2 # 4 Say if function is polynomial and to what degree: Is not a polynomial (the power of x, 9/2 is not a non negative integer).	Lesson 25 - 9.2 # 6 Say if function is polynomial and to what degree: Yes is polynomial (variable to power) and degree 6.
Lesson 25 - 9.2 # 17 For the polynomial , which is invertible (has an inverse) (a) Graph y = f(x), note is invertible since flip across x-axis and y-axis yields the same graph (passes horizontal line test). (a) (b)
