Solution

The correct option is B

One one onto function


We know that the given function is one one.(no line parallel to x-axis cuts the graph at more than one point). So, the correct options could be A or B.

Now we have to check whether the function is onto or into. The co-domain given for that function is (0,) . And we know that the f(x) = axranges from (0,). So the range and codomain is equal. And the function is onto. Hence the correct option will be B.
