Invertible Functions

What is the best description?

• They are both functions, but not inverse functions.

• They are inverse functions.

• They are reflected over y=x, but they are not both functions.

• They are not reflected over y=x, and they are not both functions.

To determine visually if a function is 1:1, you should use the

Q1. Is the sky blue?

• A) TRUE

• B) FALSE

TRUE or FALSE
If f is an invertible function and f(a) = b, then f^-1(b) = a.

• TRUE

• FALSE

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
