Question

Find the domain of the indicated function. Express answer in both interval notation and inequality notation ?

Answer 1

`t>=4, [4,oo)`

Explanation:

Recall that the square root function only exists for positive values. Everything under the square root must be greater than or equal to zero.

Here,

`g(t)=sqrt(t-4), t-4>=0`

So,

`t>=4, [4,oo)`
