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

• the x's and y's are switched
• the x's and y's are divided by 2
• the x's and y's are made negative
• the x's and y's are the same

Find the inverse of
f(x) = -3x + 3

• f^-1(x) = -3x + 1
• f^-1(x) = -1/3x + 1
• f^-1(x) = -1/3x - 1
• f^-1(x) = 1/3x + 1

When creating an inverse you must...

• Switch the x and y
• Solve for x
• Draw a graph
• drop that NaeNae
