f(x)= -x^2 + x^-1
f(-2)= - (-2)^2 + (-2)^-1 = -4 - 1/2 = -9/2
f(-1)= - (-1)^2 + (-1)^-1 = -1 -1 = -2
f(1) = - (1)^2 + (1)^-1 = -1 +1 = 0
The range is { -9/2, -2, 0}

Answer:
the correct answer to your question would be option c
Answer:

Step-by-step explanation:
To factorize, at first, do factorize all the terms then take the common terms out.
(a) 
This can be written as

Now, taking x commom from both the terms.

(b) 

Now, taking
common from both the terms, we have

This is the required factorization.
(c) 

This is the required factorization.
(d) 

This is the required factorization.
