Learn to evaluate a piecewise function

The video tutorial explains piecewise functions, which are composed of two different functions with specific constraints. It highlights the importance of constraints in determining which function to use based on the value of X. An example is provided to demonstrate how to evaluate a piecewise function when given a specific input, such as F of -2.

What is a piecewise function primarily composed of?

• A single continuous function

• Two or more functions with specific constraints

• A function that only works for positive numbers

• A function with no constraints

When should the first function in a piecewise function be used?

• When X is a negative number

• When X is equal to 4

• When X is greater than 4

• When X is less than 4

What do the constraints in a piecewise function determine?

• The color of the graph

• The type of numbers used

• The speed of calculation

• Which function to use based on the value of X

In the example given, what is the value of F(-2)?

• 7

• 5

• 3

• 9

How do you determine which function to use for a given input in a piecewise function?

• By choosing randomly

• By using the larger function

• By comparing the input to the constraints

• By checking if the input is positive
