The scatterplot below shows the amount of electric energy generated, in millions of megawatt-hours, by nuclear sources over a 10-year period.
The x-axis represents time (in years), and the y-axis represents energy (in million megawatt-hours)

A quadratic equation that best models the data is $y=-1.674x^2+19.76x+745.73$. According to this model, what is the predicted energy generation, in millions of megawatt-hours, for year 11?
