Question

Which function describes this graph?

Answer 1

The graph in the question is of the function f(x)=$log _{0.2}x$ which is option a.

Given a graph which is downward sloping and we are required to find the function whose the graph is.

Function is like a relationship between two or more variables expressed in equal to form. It may be a linear function,exponential function, logarithmic function or quadratic function.

In the given graph the values of y becomes negative when the curve crosses then x axis. For all x>1 the value of log x is greater than 0. So the value of $log_{2}x,log_{4}x,log_{20}x$ should be greater than 0 for x greater than 1. But in graph it is negative. That's why the graph will be of y=$log_{0.2}x$.

Hence the given graph is of the function f(x)=$log _{0.2}x$ which is option a.
