Answer:
The second and fourth statements are correct.
Step-by-step explanation:
We are given the function for the graph of:
[tex]y=-(x-0.5)^2+9[/tex]
Note that this is a quadratic function in its vertex form, given by:
[tex]y=a(x-h)^2+k[/tex]
Where a is the leading coefficient and (h, k) is the vertex.
Rewriting our given equation yields:
[tex]\displaystyle y = (-1)(x-(0.5))^2 + (9)[/tex]
Therefore, a = -1, h = 0.5, and k = 9.
Therefore, the vertex of the graph is at (0.5 ,9).
Because the leading coefficient is negative, the parabola opens downwards.
Therefore, the parabola has a maximum value.
In conclusion, the second and fourth statements are correct.
