How to make a piecewise function continous by finding the value k

The video tutorial explains how to determine the value of K that makes two functions continuous at X = 3. It involves setting up an equation, solving for K, and graphing the functions to visualize their intersection at the specified point. The process is similar to basic algebra, emphasizing the importance of both X and Y values being equal for continuity.

What is the primary condition for two functions to be continuous at a point?

• Both X and Y values must be the same.

• Only the Y values must be the same.

• The X values must be different.

• The Y values must be different.

What value of X is used to determine the continuity of the functions in the video?

• X = 5

• X = 4

• X = 3

• X = 2

What is the first step in solving for K to ensure continuity?

• Graph the functions.

• Substitute X = 3 into the equations.

• Find the derivative of the functions.

• Set the equations equal to zero.

What is the calculated value of K that makes the functions continuous?

• K = 3

• K = 1

• K = -3

• K = 0

What is suggested to visually confirm the continuity of the functions?

• Use a calculator.

• Check the derivative.

• Graph the functions.

• Solve the equations again.
