Answer:
When f(x) = 7, x is equal to 5.
Step-by-step explanation:
When looking at this graph, we are looking for where the line hits a point where y is equal to 7. That's because f(x) is essentially the same thing as y.
The point in which the graph hits y = 7 is (5, 7). This means the x value we need is 5.
