H(x) = x + 1 k(x) = x - 2 (h + k)(2) =

barxatty [35]

$h(x) = x + 1$

$k(x) = x - 2$

_________________________________

$(h + k)(x) = h(x) + k(x)$

$(h + k)(x) = (x + 1) + (x - 2) \\$

$(h + k)(x) = x + 1 + x - 2$

$(h + k)(x) = 2x - 1$

$(h + k)(2) = 2(2) - 1$

$(h + k)(2) = 4 - 1$

$(h + k)(2) = 3$
