From the graph. What is (fof)(x) at 𝑥=1?

Question

A graph showing an open point at (3,2) and a gap followed by a closed point at (1,2) and open point at (3,4). There is an outlier closed point at 4.

Using this information, draw the graph and figure out what is (fof)(x) at 𝑥=1?

Which is the correct answer from the following options:

a)1

b) 3

c) 5

d) 2

e) 4

I thought the answer is 3) 2, but I think I'm wrong, can somebody please clarify and explain to me?

Answer 1

If you put a 1 into the f function you would get a 2 out. This is from the point (1,2).

You are correct. The answer is 2.

I hope this helps!
