Suppose that the functions f and g are defined for all real numbers x as follows. f(x) = 4x^2
g(x) = x^3

Write the expressions for

(g. f)(x) and
(g-f)(x) and
evaluate (g+f)(-2).

Recall that the owner of a local health food store recently started a new ad campaign to attract more business and wants to know if average daily sales have increased. historically average daily sales were approximately $2,700. the upper bound of the 95% range of likely sample means for this one-sided test is approximately $2,843.44. if the owner took a random sample of forty-five days and found that daily average sales were now $2,984, what can she conclude at the 95% confidence level?
