Use a graphing calculator or other technology to answer the question.
Which quadratic regression equation best fits the data set?
yˆ=0.155x2−4.074x−38.910y^=0.155x2−4.074x-38.910
yˆ=0.155x2−4.074x+38.910y^=0.155x2−4.074x+38.910
yˆ=38.910x2−4.074+0.155y^=38.910x2−4.074+0.155
yˆ=38.910x2−4.074−0.155y^=38.910x2−4.074-0.155
