How to find the domain with radical in the numerator

The video tutorial explains how to handle radicals in fractions, focusing on solving inequalities to determine the domain of a function. It covers the conditions for the radicand and denominator, graphing the solution, and concludes with a discussion on variations of the problem.

What must be true about the radicand in a radical expression?

• It must be equal to zero.

• It can be any real number.

• It must be greater than or equal to zero.

• It must be less than zero.

What is the condition for the denominator in a fraction?

• It cannot be zero.

• It must be equal to zero.

• It must be less than zero.

• It must be greater than zero.

If x - 3 ≥ 0, what is the solution for x?

• x ≤ 3

• x < 3

• x ≥ 3

• x > 3

Why is zero not defined for the function discussed?

• Because zero is greater than three.

• Because zero makes the radicand negative.

• Because zero is less than three.

• Because zero is equal to three.

What is the domain of the function discussed in the video?

• From -infinity to 0

• From 0 to infinity

• From -3 to 3

• From 3 to infinity
