Okay, here we have this:
Considering the provided graph, we are going to identify the requested value of the function in the given value of x, so we obtain the following:
So what we need is to observe in the graph of the function what value the function takes when x=1, in this case we can clearly observe in the graph that when x=1 then f(x) is equal to -2. So we finally get:
When x = 1, then y=-2
