Which shows the graphs of f(x) and g(x)? 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.
