Selena Mathews · Answer 2

The range would be all real numbers

Step-by-step explanation:

In order to find (wor) (x), we need to start with the w (x) equation and then input the r (x) equation for every x in the w (x) equation.

w (x) = x - 2

(wor) (x) = (2 - x^2) - 2

(wor) (x) = - x^2

Given this equation, we know that x can be all real numbers
