Question

- the following functions.

f = {(-4,1),(5, 1), (1, -1)}
and
8 = {(5, 1), (1,4)}
2: Find (f + g)(1).​

Answer 1

(f+g)(1)

equals

3

Explanation:

(f+g)(1) is f(1)+g(1).

f(1) means what y corresponds to x=1 so f(1)=-1.

g(1) means what y corresponds to x=1 so g(1)=4.

So (f+g)(1)=f(1)+g(1)=-1+4=3.
