#### Storyboard Text

• ooohhhhh whats that
• We are going to start off learning how to solve for the domain algebraically
• F(x)=x+3
• x -9
• 2
• great gob
• don't forget to square root 9
• x -9=0
• x=+﻿﻿3x=-3
• x =9
• 2
• 2
• the teacher introduces a new concept to the students about radical functions
• in this case the x-values are both positive and negative 3
• The teacher gives the students a problem on the board and gives them advise that the domain of a rational function includes all real numbers except that equal 0
• The the teacher shows that the first step is to set the denominator to 0
• see you learn something new everyday
• thank you teacher
• the second step is to find the x values that cause the denominator to equal zero
• The domain of the function is all real numbers except x=+3, x=-3
• now the kids know how to find the domain of radical functions
