The average daily solar radiation R (in MJ/m²) received in a specific northern hemisphere city can be modeled throughout the year using a sinusoidal function, where x represents the month of the year (x = 1 for January, x = 6 for June, etc.): [br]R(x) = 7.5sin(0.523x - 2.1) + 14.5[br]Plot this function in GeoGebra for the domain [1, 12].
Based on the graph, in which month does the city receive the highest amount of solar radiation, and what is that maximum value?
