2. Does the function y = |x-2| have an inverse? Select the best answer.

A. Yes, it passes the horizontal line test.
B. No, it does not pass the horizontal line test.
C. It's inverse is y = |x| - 2
D. It's inverse is y = |x+2|

3. What is the inverse of: x + 4 ?

A.x - 4
B. x + 2
C.y + 4
D. y - 2

A. If any horizontal line touches the function more than once, the function has an inverse.
B. If any horizontal line touches the function more than once, the function is not a function.
C. If any horizontal line touches the function only once, the function has an inverse.
D. If any horizontal line touches the function only once, the function always has real roots.
