Question

x^2-5 / x^2 - 4

Answer 1

what are we doing? graphing, identifying asymptotes

Answer 2

It say's Identify the values restricted from the domain of the expression.

Answer 3

this means what "x" values cause the function to be undefined

in this case this is result of dividing by zero
when is x^2 -4 = 0

Answer 4

So 0 is the answer?

Answer 5

no you want 0 to be denominator
dividing by 0 is undefined

take denominator and set it equal to 0
solve for "x"
those "x" values give domain restrictions

--> x^2 - 4 = 0

Answer 6

Could it be 2 and -2..?

Answer 7

yep
