Understanding Functions and Their Inverses

The video tutorial explains how to use a table of values to evaluate functions and their inverses. It begins by demonstrating how to find the output of a function given an input, using a table. The tutorial then introduces inverse functions, explaining how they reverse the input-output relationship of the original function. It provides examples of evaluating inverse functions by interchanging inputs and outputs, using a table to illustrate the process. The video concludes with practical examples of finding specific values for inverse functions.

What is the purpose of using a table of values in relation to functions?

• To find the derivative of a function

• To calculate the area under a curve

• To identify inputs and outputs of a function

• To determine the slope of a line

If the input to the function f is 2, what is the output according to the table?

• -1

• 2

• 3

• 0

Given that f(x) = -3, what is the corresponding input x?

• x = 5

• x = 3

• x = 4

• x = 2

What is the relationship between a function and its inverse?

• They are identical

• They undo each other

• They are perpendicular

• They are parallel

If the input to the inverse function is -4, what is the output?

• -3

• 2

• -2

• 4

What happens to the inputs and outputs when switching between a function and its inverse?

• They remain the same

• They are multiplied by 2

• They are interchanged

• They are squared

For the inverse function, if the input is -2, what is the output?

• 1

• -1

• 0

• 2

If f inverse of x equals 1, what is the value of x?

• x = 4

• x = 3

• x = 2

• x = 1

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

• 1

• -1

• -2

• 2

If the inverse function value is 3, what is the corresponding input?

• x = 3

• x = 4

• x = 2

• x = 1
