Let f(x) be the mean of five numbers: 4, 5, 7, 9 and x. Let g(x) be the median of the same numbers.(adsbygoogle = window.adsbygoogle || []).push({});

For how many values of x, a real number, is f(x) = g(x)?

I only got 2. x = 0, 10

There are 3 though. Perhaps someone can help me find the other one.
