The total sound power, in decibels, from x objects each producing 50 decibels of sound power is given by the function f(x) = 50
+ 10 log x. Suppose each of the x objects increases its sound power by 10 decibels, so that the new total sound power, in decibels, is given by the function g(x) = f(x) +10
which shows the graphs of f(x) and g(x)?
