Could someone explain how to graph the following problem? I don't quite understand what "Graph H for 0 ≤ t ≤ 3 and 300 ≤ H ≤ 340" is asking me to do...

The National Oceanic and Atmospheric Administration (NOAA) has been measuring atmospheric carbon dioxide concentations (in parts per million) at Mauna Loa, Hawaii since 1958. The data

closely follow the pattern H(t) = 0.013t^2 + 0.81t + 316 +3.5 sin(2pi)(t), where t = 0 represents the

year 1960. (Complete dataset available at ftp://ftp.cmdl.noaa.gov/ccg/co2/trends/c…
