The domain is the set of input or x-values.

The domain of the given function includes all values between - 4 and 4, both inclusive:

• t ∈ [-4, 4]

The range is the set of output or y-values.

The range of the given function f(t) includes all values between - 1 and 2, both inclusive:

• f(t) ∈ [- 1, 2]
