Answer:
First, find the value of x:
[tex]h(5-x)=h(9)\\5-x=9\\-x=9-5\\-x=4\\x=-4[/tex]
Substitute the x-value in to the function [tex]x^{2}+x+1[/tex] and solve:
[tex](-4)^{2}+(-4)+1=16-4+1=12+1=13[/tex]
Therefore, the value of h(9) = 13.
Hope this is correct O-o
Answer:
A
Step-by-step 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.
