Question: Here is a sinusoidal regression equation that represents last year's average monthly high temperatures in Honolulu: y=4.24sin(0.51x-244) + 84.34 where x is the month written

Here is a sinusoidal regression equation that represents last year's average monthly high temperatures in Honolulu: y=4.24sin(0.51x-244) + 84.34 where x is the month written numerically (1= January, 2= February and so on) and y is the average high temperature

Due to weather phenomenon it has been predicted that the average daily temperature in Honolulu will increase by 0.2C this year. What is the amplitude of the sinusoidal function that represents this year's average monthly temperatures in Honolulu?
