What is the value of x in the
marked figure below?

F. x = 6
G. x=9
H. x = 8
1. x = 12

you have to put the graph on here with the question

step-by-step explanation:

answer: b

step-by-step explanation:

answer: (3,11) is your answer.

step-by-step explanation:

to determine whether a given function is even, we simply substitute x with -x in the expression. if the result after simplification is identical to the original equation, then the function is said to be even other wise odd.

f(-x) = (-x)^2 - (-x) + 8

      = x^2 + x +8

the resulting function is not identical to the original one;

f(-x) ≠ f(x)

therefore, f(x) is not an even function
