To predict the number of vinyl album sales in the year 2020, we need to substitute x=10 into the given function:
y = 0.12x^2 + 0.3x + 3.3
y = 0.12(10)^2 + 0.3(10) + 3.3
y = 12 + 3 + 3.3
y = 18.3
Therefore, the predicted number of vinyl album sales in the country in the year 2020 is 18.3 million.
The number of vinyl album salesy (in millions) in a country x years after 2010 can be modelled for 2010 through 2016 with the function below.
y=0.12x^2+0.3x+3.3
Use this model to predict the number of vinyl album sales in the country in the year 2020.(x=10)
