Question

Consider the following functions.f = {(-5, 2), (2, -5), (-1, -3)}and g = {(-1, 1), (-5,3)}Step 1 of 4: Find (f + g)(-1)

Answer 1

To calculate (f g)(-1), we use the definition:

`(f+g)(x)=f(x)+g(x)`

This is true if x is defined for f and g. Now, for our problem:

`(f+g)(-1)=f(-1)+g(-1)=-3+1=-2`
