What is the domain of the given function?

Question

F(t)= - 11/ sq. rt. (t)

Answer 1

The domain of a function are the values that can be assigned to the independent variable, in this case "t."

Because there is a square root involved, t is greater than or equal to 0.

Answer 2

t > 0

(0, infinity)

The domain is the allowed set of "input" values.  Since you are taking the square root of (t), it must be zero or positive if you are working only with real numbers. Since you are dividing by the square root of (t), it cannot be zero. Thus t > 0 is your domain.

Answer 3

t

Answer 4

I believe it's all positive numbers, since you can't have a negative square root.
