Question

consider the following functions.
$f = \\{(1,0),(2,3),(4,0)\\}$
and
$g = \\{(3,1),(2,-1),(-3,-2)\\}$
step 1 of 4 : find $(f + g)(2)$.

$(f + g)(2) = \square$

Explanation:

Step1: Find f(2) from set f

From $f = \{(1,0),(2,3),(4,0)\}$, $f(2)=3$

Step2: Find g(2) from set g

From $g = \{(3,1),(2,-1),(-3,-2)\}$, $g(2)=-1$

Step3: Calculate (f+g)(2)

Use $(f+g)(x)=f(x)+g(x)$:
$(f+g)(2)=3+(-1)$

Answer:

$2$
