Question
The graph of a logarithmic function is given. Select the function for the graph from the following options:
f(x) = log x,
g(x) = log(-x),
h(x) = log(2 - x),
r(x) = 1 + log(2 - x).
Expert Solution
Step 1
Consider the figure of graph of a function-
Select function for the graph among the functions.
.
Observe from the graph that graph passes through that is, at , .
The function must satisfy these points if the figure represent their graph. Check.
Since
Implies graph of does not pass through . Therefore, the graph is not of the function .
Step 2
Similarly,
Since,
Therefore, the graph is not of the function .
Similarly,
Since,
Therefore, the graph is not of the function .
