How to evaluate a piecewise function when it contains a hole

The video tutorial explains how to evaluate functions at specific points, such as F(4), FA(-4), and F(0). It discusses the conditions under which different functions should be used and highlights the importance of not taking the square root of a negative number, which results in an undefined value. The tutorial also emphasizes the correct application of functions based on given conditions and provides a step-by-step approach to solving these problems.

What is the result of evaluating F of 4 in the given function?

• 4

• 2

• Undefined

• 0

Why is the result of F of 4 considered undefined?

• Because it results in a complex number

• Because it results in division by zero

• Because 4 is not in the domain

• Because it involves the square root of a negative number

When evaluating F of -4, what is the result under the square root?

• Square root of 9

• Square root of 5

• Square root of 0

• Square root of 1

Which value should not be used in the first function according to the instructions?

• 4

• -4

• 0

• 2

What is the value of the function at zero?

• Undefined

• 1

• 0

• 2
