Given the function;
[tex]f(x)=-x^2+4x-3[/tex]
We are asked to find the domain of the function.
[tex]The\: domain\: of\: a\: function\: is\: the\: set\: of\: input\: or\: argument\: values\: for\: which\: the\: function\: is\: real\: and\: defined[/tex]
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:
[tex](-\infty,\infty)[/tex]
From the graph, we can get the range as
Answer:
[tex](-\infty,1\rbrack[/tex]
