To solve this problem, we will use the following graph as reference:
From the above graph, we get that the quadratic equation represents a vertical parabola that opens downwards with vertex:
[tex](3,5)\text{.}[/tex]
The domain of the function consists of all real numbers, and the range consists of all numbers smaller or equal to 5.
Answer:
Maximum of 5, at x=3.
Vertex (3,5).
Domain:
[tex](-\infty,\infty).[/tex]
Range:
[tex](-\infty,5\rbrack.[/tex]
