Quiz #3: 11.1 Inverse

The inverse of the function f(x) is written as ...

• f ^-1(x)
• f ²(x)
• f '(x)
• f ⁺(x)

Which is f^-1(x)?

• f^-1(x)=5+(x+4)³

• f^-1(x)=4+(x+5)³

When finding the inverse of a relation, 
1st you replace f(x) with y
2nd switch the x's and y's
What do you do next?

• solve for y
• replace y with f^-1(x)
• solve for x
• find the greatest common factor

Find the inverse: f(x) = x³-1

• f^-1(x)= (x-1)/3

• f^-1(x)= (x+1)/3
