Will these products be positive or negative? How do you know? (-1) (-1) X ...X(-1) = (-1)12 12 times

(-1) X (-1) X ... X (-1) = (-1)13 13 times

i need an answer for both...​

the 3rd option is right

step-by-step explanation:

true

step-by-step explanation:

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

      2

  2 is to go somewhat to the top right of a because it is squared    

v= a h/3
