$f(x)=2\log x$
$f(x)=2\log x$ (the base of the common logarithm is 10.) Create a table of function values. For x, select powers of $10$, since $\log 10^{n}=n$ $\left[\begin{array}{lllllll} x & 1/10 & 1 & \sqrt{10} & 10 & 100 & \\ f(x) & -2 & 0 & 1 & 2 & 4 & \end{array}\right]$ Plot the points and join with a smooth curve.
