The domain of (x+1)/(x^2 + 2x - 3) is a. all real numbers
b. all real numbers except 1 and -3.
c. all real numbers except -1.
d. all real numbers except -3, -1, and 1.
e. all real numbers except -3.

Find the domain by finding where the expression is defined.

Interval Notation:

(-∞,−1)u(-1,3)u(3,∞)

Set-Builder Notation:

{xlx≠-1,3}

Step-by-step explanation:hope this helps

false

step-by-step explanation:

4y - 6 + 4y^2 - 9

before simplifying this contains 4 terms

after simplifying

4y -15 + 4y^2

it contains 3 terms
