Ecological Impact of Noise Pollution

Consider a local industrial area that monitors the concentration of sulfur dioxide (SO2) over time. A sensor records pollutant concentration, modeled by the linear function $$f(t) = 0.5*t + 10$$ where $$t$$ is the time in hours (with $$0 \le t \le 4$$) and $$f(t)$$ is measured in parts per million (ppm). All of the following statements about the function and its implications are true except:
