How to evaluate the limit of a constant function

The video tutorial explains constant functions, focusing on graphing F of X = 13 as a horizontal line. It discusses evaluating the function at X = 5, emphasizing the continuity of the function and the concept of limits. The tutorial aims to simplify understanding of these mathematical concepts.

How is the graph of F(x) = 13 represented?

• As a horizontal line

• As a vertical line

• As a diagonal line

• As a curve

What is the height of the function F(x) = 13 at X = 5?

• 13

• Undefined

• 5

• 0

When approaching X = 5 from both sides, what value does the function approach?

• 0

• 5

• 13

• Infinity

Why can't we directly substitute X = 5 into the function?

• Because the function is not defined at X = 5

• Because the function is discontinuous

• Because the function is constant

• Because the function is undefined

What does the limit of the function at X = 5 indicate?

• The function is undefined

• The function is continuous

• The function has a limit of 13

• The function has a limit of 0
