SOLUTION: Given the function k described by k(x) = x + 18, find each of the following. k(0) = _? k(-13) = _? k(-5) = _? k(6) = _? k(b + 19) + _?

Hi,         

One completes the question(s) by simply substituting the value given for x

k(x) = x + 18

k(0) = 0 + 18 = 18

k(-13) = -13 + 18 = 5

k(-5) = -5 + 18 = 13

k(6) =  6 + 18 = 24

k(b + 19) = (b+19) + 18 = b + 37
