Answer:

The answer is B.

Step-by-step explanation:

The formula is;

[tex]g(x)=4-(x-6)^2[/tex]

Maximum value of the function is where the x value makes (x-6)^2 equals to 0. Then;

[tex](x-6)^2=0\\x=6[/tex]

Breaking point of the function is x=6. When we put 6 instead of x, the function will go to:

[tex]g(6)=4-(6-6)^2\\g(6)=4[/tex]

When we put x=4, the function will go to;

[tex]g(4)=4-(4-6)^2=4-2^2=0[/tex]

Then the solution is increasing: x < 6; decreasing: x > 6
