Question

F= ((-5,1),(2,2),(1,-2))g=((2,-5),(-4,-2),(1,1))Find (f+g)(1)

Answer 1

To find (f+g)(1), we can start by rewriting it as:

`(f+g)(1)=f(1)+g(1)`

The function f and g have a set of pairs. We are looking for the pairs that have the first number "1", we want the second number. In both, they are the last pair.

For f this is (1,-2), so:

`f(1)=-2`

For g this is (1,1), so:

`g(1)=1`

So, substituting into the first expression, we have:

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