This is the graph of $g(x)=\log(-x)$
We first find the graph of $f(x)=\log x$ among the graphs 32 - 35. $f(x)=\log x$ has a graph that is - defined for positive x only (only graph 35) - rises from left to right (only graph 35) - passes through (1,0) (graphs 34 and 35) - passes through (10,1) (only graph 35 can do this) Conclusion: graph 35 is the graph of $f(x)=\log x$. Graph 32 (this graph) is obtained from the graph of $f(x)=\log x$ by reflecting it about the y-axis. This is the graph of $f(-x)=\log(-x)=g(x)$
