Answer 1

Answer:

$(f+g)(1)=0$

Step-by-step explanation:

We are given that:

$\displaystyle f=\left\{(-2, -5), (3, -1), (1, -1)\right\}\text{ and } \\ \\ g = \left\{(1, 1), (-1, -2), (-4, 1), (-3, -1)\right\}$

And we want to find the value of (f + g)(1).

Recall that this is equivalent to:

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

According to the set, f(1) = -1 and g(1) = 1. Hence:

$=(-1)+(1)=0$
