Answer:

A

Explanation:

Since we need to find the value of h(9), we can substitute the (5-x) part from the original equation with 9 to get the value of x, which is 5-x = 9, x = -4. With that, we can go ahead and plug the x into the right side of the equation to get (-4)^2 + (-4) + 1, which equals 16 - 4 + 1, which equals 13.

I hope this helped! Please do let me know if you have further questions :D

Answer:

First, find the value of x:


h(5-x)=h(9)\\5-x=9\\-x=9-5\\-x=4\\x=-4

Substitute the x-value in to the function
x^(2)+x+1 and solve:


(-4)^(2)+(-4)+1=16-4+1=12+1=13

Therefore, the value of h(9) = 13.

Hope this is correct O-o
