Answer:

The second and fourth statements are correct.

Explanation:

We are given the function for the graph of:


y=-(x-0.5)^2+9

Note that this is a quadratic function in its vertex form, given by:


y=a(x-h)^2+k

Where a is the leading coefficient and (h, k) is the vertex.

Rewriting our given equation yields:

\displaystyle y = (-1)(x-(0.5))^2 + (9)

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.
