Question

Consider the following functions.

f={(3,2),(−1,5),(−3,−4),(2,4)}

and

g={(−1,2),(−3,−4),(−5,2),(5,1)}

 

Find (f+g)(−1)

Answer 1

Hi Joana,

Consider the following functions.

f={(3,2),(−1,5),(−3,−4),(2,4)}

and

g={(−1,2),(−3,−4),(−5,2),(5,1)}

 

Find (f+g)(−1)

This is asking you to add the function values f(-1) and g(-1) together.

So, if the input (x) for function f is -1, the output (y) is 5.

If the input (x) for function g is -1, the output is 2.

Now all you have to do is add the two outputs. I'll bet you can finish from there.
