Given the polynomial function below, find f(-1). f(x) = -x ^3 - x ^2 + 1

Step-by-step explanation:

Given

f(x) =

Finding f(-1) means, we have to put -1 in the places of x in the function,

So, putting x=-1 in the function

As the power 3 is odd, the minus will remain the same, while in the 2nd term minus will be eliminated due to even power. So,

=>

=> 1

Hence,

the best buy, is the 4- kilogram bag of lollipops for $18.40.

step-by-step explanation:

i found my answer by dividing the cost of each bag by their respective weights.

14.88 divided by 2 = 7.44

17.29 divided by 3 = 5.77

18.4 divided by 4 = 4.6

24.4 divided by 5 = 4.88

by this, i found that the 4 kilo bag is the best buy.

the answer is 48m^2!
