Exploring Square Root and Cube Root Graphs

What is the first step in graphing the basic square root function?

• Pick positive numbers only

• Pick negative numbers only

• Pick both positive and negative numbers

• Pick imaginary numbers

Why can't we graph the square root of negative numbers?

• They are too large

• They are imaginary

• They are undefined

• They are too small

What is the domain of the basic square root function?

• All numbers less than zero

• All numbers greater than or equal to zero

• All positive numbers

• All real numbers

What is the range of the basic square root function?

• All real numbers

• All numbers less than zero

• All positive numbers

• All numbers greater than or equal to zero

What is the cube root of 0?

• 1

• 0

• 8

• Negative 1

What is the cube root of 8?

What happens to the cube root function as you go further to the left?

• It becomes undefined

• It goes down

• It goes up

• It stops

What will be the next step after understanding the basic functions?
