The table represents the function f(x).

when f(x) = –3, what is x?

–29

–10

–3

–1

x=-1

Step-by-step explanation:

f(x)=3 on the chart lines up with -1 as the x value

-1

Step-by-step explanation:

Find -3 in the column for f(x).

Going to the x column for this value, the number is -1.  This means when f(x)=-3, then x=-1.

-22

times both sides by 2, times () by 8, add alile terms, move terms, add alike and caculate divide both sides by 3

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
