Ella collects dimes, quarters, half dollars, and $1 coins in her piggy bank. When she opens it, the number of dimes equals the number of half dollar coins. The number of quarters also equals the number of $1 coins. Knowing that there is at least one of each coin in the piggy bank and that the value of the coin collection is between $10 and $12, find the number of unique possible combinations of coins in the collection.

answer: city needs 2.4 inches of rainfall more to match the record of 40 inches.

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
