Using interval notation, identify the implied domain of the restricted function

Question

Using interval notation, identify the implied domain of the restricted function f(t)=2(e)^t with image [1,6]. Express each value in its unrounded, exact form.

Answer 1

Assuming you mean f(t) = 2e^t with range [1,6].

Dividing both sides by 2, then solving for t we get

For the range [1,6] we have
