Question 22650:  What is the range of the function f(x) = -x - 3, when the domain is {-1, 0, 4, 7}? 
 Answer by rapaljer(4671)      (Show Source): 
You can  put this solution on YOUR website! Substitute the values of x to see what you get for f(x):
 
f(x) = -x - 3 
f(-1) = -(-1) - 3 = -2 
f(0)  = -0 - 3= -3 
f(4) = -4 - 3 =-7 
f(7) = -7-3 = -10
 
 
Range is the set of all y-values, or in this case, all f(x) values, so  
Range = { -2, -3, -7, -10}
