Question 1047622:  I need help understanding this question. I'm plugging the values in for x but apparently that's not how to get the correct answer or I am doing it wrong. 
 
Evaluate the function at the indicated values. 
k(x) = −x2 − 2x + 3; 
     
k(0), k(2), k(−2), k(2), k(a + 2), k(−x), k(x2)

You can  put this solution on YOUR website! Evaluate the function at the indicated values. 
k(x) = −x^2 − 2x + 3;
 
k(0) = -0^2 - 2*0 +3 = 3 
------------------------- 
k(2) = -2^2 - 2*2 + 3 = -4-4+3 = -5 
----------------------------------- 
k(−2) = -(-2)2 -2*-2 + 3 = -4 +4 + 3 = 3 
----------------------------------------- 
Can you take it from there? 
Cheers, 
Stan H.
