Answer :

To determine the domain of the function [tex]\(\sqrt[4]{3 t - 3}\)[/tex], we must ensure that the expression inside the fourth root is non-negative because the fourth root of a negative number is not real.

The steps to find the domain are as follows:

1. Set up the inequality: To find the domain, the expression inside the fourth root, [tex]\(3t - 3\)[/tex], must be greater than or equal to zero:

[tex]\[ 3t - 3 \geq 0 \][/tex]

2. Solve the inequality: Solve the inequality for [tex]\(t\)[/tex]:

[tex]\[ 3t - 3 \geq 0 \][/tex]

Add 3 to both sides of the inequality:

[tex]\[ 3t \geq 3 \][/tex]

Divide both sides by 3:

[tex]\[ t \geq 1 \][/tex]

3. Write the domain: The solution to the inequality is [tex]\(t \geq 1\)[/tex]. This means that the value of [tex]\(t\)[/tex] must be at least 1. In interval notation, the domain of the function is:

[tex]\[ [1, \infty) \][/tex]

Therefore, the domain of the function [tex]\(\sqrt[4]{3 t - 3}\)[/tex] is [tex]\( t \in [1, \infty) \)[/tex].
