Determining If Functions Are Inverse

Find the inverse of the function
f(x) = 3x − 5

• f^-1(x)=3x +5

• f^-1(x)=(x+5)/3

• f^-1(x)=3y-5

• f^-1(x)=3y+5

What operation allows us to verify if functions are inverses?

• Multiplying

• Dividing

• Adding

• Composing

What is the inverse of this function?

• A

• B

• C

• D

Find the inverse of f(x) = -4x - 12

• f^-1(x) = 4x - 3

• f^-1(x) = -1/4x - 3

• f^-1(x) = 1/4x + 3

• f^-1(x) = -4x - 3

Are the blue and red graphs inverse functions?

• yes

• no

• no way to tell

Is the inverse function found correctly?

• yes

• no

An ​ (a)   takes a previously found result ( a y value) and returns it to its original value (x value). This means you are ​ (b)   a function

• function

• inverse

• 2 or more

• undoing

Was the inverse function found correctly?

• no,

• yes
