Question

consider the following functions.
$f = \\{(1, -1), (-2, 4)\\}$
and
$g = \\{(5, 0), (1, 4), (-1, 0), (-2, 5)\\}$

$(f + g)(1) = \square$

Explanation:

Step1: Find $f(1)$ from set $f$

From $f = \{(1, -1), (-2, 4)\}$, $f(1) = -1$

Step2: Find $g(1)$ from set $g$

From $g = \{(5, 0), (1, 4), (-1, 0), (-2, 5)\}$, $g(1) = 4$

Step3: Calculate $(f+g)(1)$

$(f+g)(1) = f(1) + g(1) = -1 + 4$
