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/co2_mm_mlo.txt.)

1. Explore the CO2 concentration model for the period 1960 – 1962.
a) Graph H for 0 ≤ t ≤ 3 and 300 ≤ H ≤ 340
