Questions: The bar graph shows the average atmospheric concentration of a pollutant in ppm for seven selected years. The data can be modeled by the functions f(x)=1.27x+310 and g(x)=0.01x^2+0.6x+313 where f(x) and g(x) represent the average concentration of pollutant in ppm x years after 1950. Complete parts (a) through (c). a. Find and interpret f(40). Use the equation for f(x) to identify this information as a point on the graph. (Type an ordered pair.)

The data can be modeled by the functions $f(x)=1.27 x+310$ and $g(x)=0.01 x^{2}+0.6 x+313$ where $f(x)$ and $g(x)$ represent the average concentration of pollutant in $\mathrm{ppm} x$ years after 1950. Complete parts (a) through (c). a. Find and interpret $\mathrm{f}(40)$. Use the equation for $\mathrm{f}(\mathrm{x})$ to identify this information as a point on the graph. $\square$ (Type an ordered pair.)
