Bottled Water Sales Annual U.S. per capita sales of bottled water in the period 2007–2014 could be approximated by R ( t ) = 0.25 t 2 − t + 29 gallons ( 0 ≤ t ≤ 7 ) , where t is time in years since 2007. According to the model, were annual U.S. per capita sales of bottled water accelerating or decelerating in 2009? How fast? [ HINT: See Example 2.]

Consider the graphs of y = f(x) and y = g(x) in the given diagram
y= f(x).
y = g(x)
Evaluate (f+g)(2) -5
Determine all for which g(x) < f(x)
Determine all for which f(x) +3 = g(x)
I) For what value(s) of x does g(x) = -4? Separate multiple answers with commas as needed.
J) Give the interval(s) of such that g(x) > 0. Use the union symbol between multiple intervals.
K) Give the interval(s) of such that g(x) <0. Use the union symbol between multiple intervals.
