Use polynomial graph shape and end behavior to determine which of the following could be the x-coordinates at which the relative
maximum and relative minimum occur in the given function.
f(x) = -10x^3+6x-2

so, converting firstly the mixed fractions to improper fractions and then "adding".

answer:   c ?

step-by-step explanation:

b.

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
