Round numeric answers to four significant digits. The volume of a gas was measured as the temperature was increased from 173 K to 423 K in 50 K intervals. The gas volumes recorded, starting at 173 K, were 18, 23, 28, 34, 40, and 45 cm^3. Determine whether the data is best described by an increasing or decreasing, and linear or exponential function. Find the regression equation. Let f(x) be the volume and x be the temperature.
The data is_.
f(x)= _
