Question

If r(x) = 2 – x2 and w(x) = x – 2, what is the range of ? (w0r)(x)

Answer 1

Answer: The answer is A

Step-by-step explanation:

Answer 2

Answer:

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
