The ten basic functions in our toolkit are increasing on their entire domain is option d) x, x³, √√x, ex, In(x)
What is the domain  function about?
The function  x, x³, √√x, ex, In(x) is known to be increasing the the entire domain because it is following the property of function.
Note that A function is said to be one that shows the association that tends to exist between two sets of data, where there is one input and also another output.
Hence, A relation is seen as a function when and only if all of the input data is linked to exactly one output data and this is with the case of   x, x³, √√x, ex, In(x).
Therefore, The ten basic functions in our toolkit are increasing on their entire domain is option d) x, x³, √√x, ex, In(x)
