Given:

The parabola equation is,


f\mleft(x\mright)=-3\mleft(x-3\mright)^2+3

To find:

domain and range of the graph.

Step-by-step explanation:

Domain:

The domain of a function is the set of input values for which the function is real and defined.

the function here dose not have any undefined points. So,

the domain is,


-\infty\: Range;<p>The set of values of the dependent variable for which the function is defined.</p><p>for parabola ,</p>[tex]ax^2+bx+c\:

with the vertex,


(x_v,\: y_v)
\begin{gathered} if\: a<0\: \text{ the range is,}f\mleft(x\mright)\le\: y_v \\ \text{if }\: a>0\text{ the range is, }f\mleft(x\mright)\ge\: y_v \end{gathered}

then,


\begin{gathered} a=-3 \\ \text{vertices: (}x_v,\: y_v)=(3,\: 3) \end{gathered}

hence,


f\mleft(x\mright)\le\: 3

The maximum point is (3,3).

Final Answer:

Domain of the parabola is,


-\infty\: <strong>Range of the parabola is,</strong>[tex]f\mleft(x\mright)\le\: 3

in interval notation the range is,


\: \: (-\infty\: ,\: 3\rbrack

the vertex of the parabola is,


(3,3)
