Answer:
Domain → (-∞, -1)∪(-1, ∞)
Range → (-∞, ∞)
Step-by-step explanation:
Given function is,
This function is not defined when the denominator is zero.
2x + 2 = 0
2x = -2
x = -1
Therefore, x = -1 is not in the domain of this function.
And the domain will be,
(-∞, -1)∪(-1, ∞)
For all values of x (except x = -1) we get some output values (value of ).
Therefore, range of the function will be (-∞, ∞).
Answer:
A rational expression that has the nonpermissible values and
is
.
Step-by-step explanation:
A rational expression has a nonpermissible value when for a given value of , the denominator is equal to zero. In addition, we assume that both numerator and denominator are represented by polynomials, such that:
(1)
Then, the factorized form of must be:
(2)
If we know that , then the rational expression is:
(3)
A rational expression that has the nonpermissible values and
is
