Given:
We get the point (0,4) from the graph.
Recall that the vertex of a parabola is the point at the intersection of the parabola and its line of symmetry.
[tex]\text{Vertax =(0,4)}[/tex]
Every single number on the x-axis results in a valid output for the function.
The domain of the parabola is real values.
[tex]\text{Domain}=(-\infty,\infty)[/tex]
The maximum value of y is 4 and the parabola is open down.
[tex]Range=(-\infty,4\rbrack[/tex]
Final answer:
[tex]\text{Vertax =(0,4)}[/tex]
[tex]\text{Domain}=(-\infty,\infty)[/tex]
[tex]Range=(-\infty,4\rbrack[/tex]
