Markus Copeland · Answer 1

f (-3) = - -3 + 4 = 3+4 = 7

f (-2) = - -2 + 4 = 2+4 = 6

f (-1) = --1 + 4 = 1+4 = 5

f (1) = - 1 + 4 = 3

Range : {3,5,6,7}

Choice A

Greenie · Answer 2

If we substitute x = - 3 in f (x) we have - -3 + 4 = 7 which is one element in the range.

Doing the same calculation for x, - 2, - 1 and 1 we get 6, 5 and 3
