The correct answer is C

Explanation

The graph of the function g is the same as the graph of the function f translated up 4 units. The function f intersects the x-axis three times, but if the graph is shifted up 4 units, then the graph will intersect the x-axis only twice. Therefore, function g of x is equal to 0 for exactly two values of x between negative 5 and 15.
