To find the domain of the function, we need to determine the values of t for which the function is defined.
The function is defined as long as the expression under the square root is non-negative. So, we set the expression greater than or equal to zero and solve for t:
t - 9 ≥ 0
Adding 9 to both sides gives:
t ≥ 9
Thus, the domain of the function is [9, ∞) in interval notation.
