find the range of f(x)=-2x-5 for the domain (-2, -1, 1, 2)

The range will be the list of y values generated by putting each of the x values into the function.......thus, the range  is  { -9, -7, -3, -1 }   for the associated x values { -2, -1, 1, 2 }

What about finding the range for f(x)=-2x+5 with domain {1,2,3,4}  ????
