Understanding Discrete Functions

The video tutorial explains how to use a function F of X, represented as a list of ordered pairs, to evaluate specific values and determine corresponding inputs or outputs. It covers evaluating F of 8 and F of 0, as well as finding X when F of X equals 8 and 0. The tutorial emphasizes understanding the relationship between inputs (X values) and outputs (Y values) in a discrete function.

What is a discrete function typically represented by?

• A single equation

• A list of ordered pairs

• A set of inequalities

• A continuous graph

In a function, what does the input correspond to?

• The Y value

• The Z value

• The X value

• The constant

What is the relationship between input and output in a function?

• Output determines input

• Input determines output

• Input equals output

• Input is always greater than output

What is the output of the function F when the input is 8?

• 12

• 8

• 36

• 0

If F(x) = 8, what is the corresponding input value?

• 36

• 8

• 12

• 0

What is the function value when the input is 12?

• 0

• 36

• 12

• 8

What is the output of the function F when the input is 0?

• 0

• 8

• 12

• 36

If F(x) = 0, what is the corresponding input value?

• 8

• 12

• 4

• 0

What is the output when the input is 4 in the function F?

• 12

• 0

• 4

• 8

What is the key takeaway when given the function value?

• You are given the X value

• You are given neither X nor Y values

• You are given the Y value

• You are given both X and Y values
