Problema Solution
The GDP (Gross Domestic Product) of the United States, which measures the size of the economy in trillions of dollars, is projected to be given by the function:
f(x) = .052x2 + .264x +9.9
where x corresponds to the year 2000.
Estimate the GDP in 2015
Answer provided by our tutors
since x corresponds to 2000
x + 15 will correspond to 2015
f(x + 15) = 0.52*(x + 15)^2 + 0.264*(x + 15) + 9.9
f(x + 15) = 0.52*(x + 15)^2 + 0.264*(x + 15) + 9.9
by multiplying and simplifying we get
f(x + 15) = 0.052*x^2 + 1.824*x + 25.56 is the GDP for 2015.
