What is the domain for the following function?

Y = (x+1) / (x^2+x-6)

A) {x does not equal - 1}

B) {x does not equal - 3; x does not equal 2}

C) {x does not equal - 3}

D) {x does not equal 0}

it's B

Step-by-step explanation:

the set of numbers for which a function is defined is called a domain of a function

if a number is not in the domain of a function, then the function is undefined for that number

denominator must not be zero

if we plug - 3 then the y

= (-3+1) / (9+-3-6)

= (-2) / 9-9

=-2/0

which is undefined for x=-3

now

if we plug 2 we have

(2+1) / (4+2-6)

=3/0

the function is undefined for x=2

so

x≠3, x≠2
