Q1: Lesson 2 | Rational Functions

Question 1

is a mathematical expression consisting of variables, coefficients, and the operations of addition, subtraction, multiplication, and non-negative integer exponents.

Answer 1

polynomial

Question 2

is formed by dividing a polynomial function by another polynomial function.

Answer 2

rational function

Question 3

is the set of first coordinates.

Answer 3

domain

Question 4

can be find by getting the inverse of the rational function and determining its domain. If it does not work, the best way is to graph the rational function.

Answer 4

range

Question 5

is the set of second coordinates

Answer 5

range

Question 6

They are the restrictions on the x-values of a reduced rational function.

Answer 6

vertical asymptotes

Question 7

Answer 7

oblique asymptotes

Question 8

is an apparent solution that does not solve its equation.

Answer 8

extraneous solution
