PLEASE ANSWER NEED HELP!! THANKS :)
A tomato grower needs to ship early when prices are high and spoilage is low. She now has 20 tons of tomatoes on hand and can add five tons a week by waiting to ship them. The current profit is $200 per ton but it will reduce by $20 per ton for each week she delays. When should she ship to receive maximum profit?

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
