You got the graph. f(x) is the same as y, so the question is asking what x is if y = 7. Look at the graph, and you'll see that when y = 7, the x is -3.

The slope appears to -1 for x you go to the right one, you go down one so (-2,6) is a point on the graph the slope is negative so we will reach 7 to the left of that reverse the slope so every point you go the left , you should go one up so (-3,7) x = -3 give f(x) = 7 alternatively , the horizontal line at the top of the graph is y =7 where does it cross you line, at x = -3
