Need help with this question, thank you tutor!

4. Marjory Dufn is still toying with various models to fit to the New York sea level gures she had seen after purchasing a beachfront condominium in New York. The following is a cubic curve she obtained using regression: L(t) = 0.0001:3 + 0.022:2 + 2.22' mm (millimeters) (t is the time in years since 1900). The function L(t) gives the sea level measured in New York for various years relative to the 1900 level L=0 mrn. So L = 10 mm, means that the sea level in that year was 10 mm higher than the 1900 level. A) Use either graph paper or an online graphing calculator like www.desmos.com to graph this function over the period 1900 to 2025. Label both axes on your graph with units and appropriate scales. Glue or tape your graph in the space below. Do NOT include a hand drawn graph. B) Compute L'(90). Show work and include units with your value. 0) Interpret your answer following the general guidelines for interpreting derivatives located in the Files area of Canvas. Use complete English sentences. D) When, to the nearest year, was the sea level rising at the greatest rate? What is this rate? Include units and SHOW WORK
