Identify the functions in the graph and match the columns
The graph of x12 and x14 will be similar. √x and x14 are not defined for x<0.
So these graphs will only be plotted for +ve values of x. Once we identify the two graphs we have to distinguish between x12 and x14. For that we can look at the interval[0,1]. x14 is greater than x12 in that interval.
For example,(116)14 > (116)12 because 12 > 14.
So the graph of x14 will be alone x12 in the interval (0,1).
The other two graphs will be of x13 and x15. We can distinguish between these two graphs the same way we did for x12 and x14.
The graph which lies above will be the graph will be the graph of x15 in the interval (0,1).
