Given the function;


f(x)=-x^2+4x-3

We are asked to find the domain of the function.


The\: domain\: of\: a\: function\: is\: the\: set\: of\: input\: or\: argument\: values\: for\: which\: the\: function\: is\: real\: and\: defined

Looking at the function and the given graph, we can see that function does not have any domain constraints.

Therefore, the domain using interval notation is

Answer:


(-\infty,\infty)

From the graph, we can get the range as

Answer:


(-\infty,1\rbrack
