Consider the following functions:

f = { (-4, 2), (1, - 1) } and g = { (0, 3), (1,2), (-3,-2), (-4,2) }

(f+g) (1) = ?

1

Step-by-step explanation:

(f+g) (1) = f (1) + g (1) = - 1 + 2 = 1

__

The pair (1, - 1) in the definition of f tells you f (1) = - 1.

The pair (1, 2) in the definition of g tells you g (1) = 2.
