Question 346679: Sketch the graph of y=1.5(2)^2. State the functions domain and range.
I've already done the graph, all I need is the function's domain and range.
Thank you so much for all of your help!!!!!

You can put this solution on YOUR website!
You have a constant function. Since  is not a factor in your function, it doesn't matter what is. Therefore the domain is all reals, i.e.  . Since the value of  is a constant 6, the range is  , more simply stated  .
On the other hand, if you really meant:
then, since this is a polynomial function, it is defined for all real , hence the domain is still all reals, or . Since this is a parabola opening upward with vertex at ) , the minimum value of the function is 1.5 and the maximum increases without bound. Hence the range of the function is:  .
