Although the y-values will increase towards + on our data only includes the approximations for the first 90 years, starting from the waste from 1960 (6200) to 2050 (6,620,000), which would be establish our range as (6200 - 6,620,000) Transformations: The Base Function 1.090394 is Vertically Stretched by a factor of 6200 ( A = 6200 ) . No Horizontal Stretch . No Vertical Shift Up or Down and No Horizontal Shift Right or Left good Restrictions / Limitations in the Real World: The only restriction of the example is that x > 0 and y > 6200 as you cannot have a negative amount of years, and our data starts from the year of 1960, where the plastic waste is 6200 tons. Graph Cumulative Plastic Wate On The Surface Ocean (Tons) 100 0DC 10 180 Calculations and Predictions: *Using Our Equation to Approximate Plastic Waste for the year of 2080 Since x at 0, corresponds to the year of 1960, x corresponding to 2080 would be 120 (2080 - 1960). 1.09839 {" Y =6200 & 1.09839 120 Y =6200 Y =482,147,732.7 Therefore, according to my calculations, in the year of 2080, there will be approximately 482,147,732.7 Tons of Plastic Waste in the Surface Ocean. excellent Citations
