On a semi-log plot (linear x-axis, logarithmic y-axis), a straight line represents an exponential function of the form f(x) = A·10^(kx). The line's intercept at x = 0 gives A, and its slope (in decades per unit x) gives k.
From the graph, the line passes through (x=0, f=0.1) and (x=3, f=100). At x = 0: f(0) = A·10^0 = A = 0.1 At x...
