The scatter plot shows the price, in cents, of a postage stamp used to mail a letter in the Unites States for the years from 1958 to 2014. Also shown is a line of fit to model the
data.
The equation of the line of fit is y = -0.71 + 0.86x, where y represents the predicted
price, in cents, of a stamp and x represents the number of years since 1958.

investment b is an ordinary annuity with $3,909.64 in the account after one year.

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
