Question

Consider the following functions:

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

(f+g)(1)= ?

Answer 1

1

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.
