the number of cases of a new diease can be modeled by the quadratic
The number of cases of a new disease can be modeled by the quadratic regression equation y = –2×2 + 36x + 6, where x represents the year
Hope it will be Helpful
The number of cases of a new disease may be modeled by the quadratic regression equation y=-2x^2+44x+8 , what is the best prediction for the number of cases after 20 years ( the carrot symbol (^) means the following number is the exponent)
