The video tutorial explores the domain and range of radical functions, focusing on square roots. It explains how the parameter 'a' affects the function's vertical stretch, direction, and range. The domain is determined by the values under the square root, which must be non-negative. The parameters 'H' and 'K' shift the function horizontally and vertically, respectively, influencing the domain and range.

What is the primary focus when analyzing the domain and range of radical functions?

• The behavior of the function as X approaches infinity

• The effect of imaginary numbers

• The inclusion of square roots as the parent function

• The impact of odd roots

How does the parameter 'a' affect a radical function when it is between 0 and 1?

• It has no effect

• It stretches the function horizontally

• It makes the function go up slower

• It flips the function over

What happens to the range of a radical function if 'a' is negative?

• The range increases

• The range decreases

• The range becomes undefined

• The range remains constant

What does the parameter 'a' do if it is greater than 1?

• It has no effect

• It flips the function over

• It makes the function go up slower

• It stretches the function vertically faster

What happens to the range if 'a' is positive?

• The range increases

• The range remains constant

• The range becomes undefined

• The range decreases

What is the effect of 'a' being negative on the function?

• It flips the function over

• It makes the function go up faster

• It stretches the function horizontally

• It has no effect

What does 'a' do if it is between 0 and 1?

• It flips the function over

• It has no effect

• It stretches the function vertically faster

• It makes the function go up slower

What happens to the range if 'a' is positive?

• The range becomes undefined

• The range decreases

• The range remains constant

• The range increases

What is the effect of 'a' being negative on the function?

• It has no effect

What condition must the interior of a square root meet in a radical function?

• It must be less than zero

• It must be greater than zero

• It must be greater than or equal to zero

• It must be equal to zero
