Pre calculus question too easy?

There's a question in my textbook that asks me: "Find two different values of x such that g(x) = ?7." Above it gives me a table chart that shows the values of x and g(x):

x.....| g(x)
3.....| 3
8.....| ? 7
8.4..| ? 7

and so on.

I think my answers are 8 and 8.4, but is it really that easy? It just seems a little bit too obvious...
