Find the domain and range of 1/t+2

Domain = (-∞, - 2) ∪ (-2, ∞).

Range = (-∞, 0) ∪ (0, ∞).

Step-by-step explanation:

t can't have the value - 2 because that would make 1 / (t + 2) = 1/0 which is undefined.

So the domain is All real values of t. except t = - 2.

As t approaches infinity or negative infinity f (t) approaches zero, and as t approaches - 2 from below or above f (t) approaches negative infinity or positive infinity.
