b) Graphing technology was used to determine a linear and an exponential model for the data. The following regression was performed. Write the linear equation of best fit and the exponential equation of best fit. LinReg y = ax + b a = -50 b = 3000 r² = 1 r = -1 c) The following is a graph of both models. Label the axes and each graph. How long does it take before the graphs show a visible difference? 3000 4.. 2800- 2600 2400 2200- 2000- 1800- 1600 1400- 1200 1000- 800 600 400 ExpReg y = a b^x a = 3001.498529 b= 0.9827503405 r² = 0.9998385107 r= -0.9999192521 200 20 22 24 d) Dwight left the tank overnight. The next morning, after 14 hours, the pressure was 2300 psi. Which model predicts this pressure most accurately?
