The function

is not defined for t = -2, as this value requires division by zero.

Hence the domain of f(t) is

"all real numbers except -2"

Also, no matter how large or small t becomes, f(t) will never be equal to zero.

So the range of f(t) is

"all real numbers except zero".

We can see in the graph that the function is not defined for t = -2 and that the function takes all values except 0.
