What is the range of the table?

{ (0, 0), (2, -4), (3, 3), (-2, 1) }

What is the definition of function?

Every input has only ONE output

Inputs have different outputs every time

For the function {(0,1), (1,-3), (2,-4), (-4,1)}, write the domain and range.

D: {1, -3, -4,} R: {0, 1, 2, -4}

D:{0, 1, 2, 3, 4} R:{1, -3, -4}

What is the definition of function composition?

Function composition is the operation of applying one function to the results of another, defined as (f∘g)(x) = f(g(x)).

Function composition is the process of adding two functions together to create a new function.

Function composition involves multiplying two functions to find their product.

Function composition is the method of finding the inverse of a function.

What is the definition of function subtraction?

Function subtraction is the operation of subtracting one function from another, defined as (f-g)(x) = f(x) - g(x).

Function subtraction is the operation of adding one function to another, defined as (f+g)(x) = f(x) + g(x).

Function subtraction is the operation of multiplying one function by another, defined as (f*g)(x) = f(x) * g(x).

Function subtraction is the operation of dividing one function by another, defined as (f/g)(x) = f(x) / g(x).

What does f(g(x)) represent?

The composition of functions, where g(x) is substituted into f(x).

The difference between f(x) and g(x).

What does it mean to find the inverse of a function?

the x's and y's are divided by 2

the x's and y's are made negative

What does an inverse function do?

Does the opposite of the original function

If f(x) is a function with the following steps: 1. Add 3 2. Multiply by 5 How would we write the inverse function, f -1 (x)?

f − 1 ( x ) = x 5 − 3 f^{-1}\left(x\right)=\frac{x}{5}-3 f − 1 ( x ) = 5 x − 3

f − 1 ( x ) = x − 3 5 f^{-1}\left(x\right)=\frac{x-3}{5} f − 1 ( x ) = 5 x − 3

f − 1 ( x ) = 3 − x 5 f^{-1}\left(x\right)=3-\frac{x}{5} f − 1 ( x ) = 3 − 5 x

f − 1 ( x ) = 5 ( x + 3 ) f^{-1}\left(x\right)=5\left(x+3\right) f − 1 ( x ) = 5 ( x + 3 )
