Quizplus · Accepted Answer

The average rate of change is given by the formula (f(b)-f(a))/(b-a). In this case, a = 11ebfe6a_2cbc_eefc_96cc_43744dec039d_TBX8650_11 = -4 and b = 11ebfe6a_2cbc_eefd_96cc_c92da40287d3_TBX8650_00 = 4. Plugging in the values, we get (-6-(-4))/(4-(-4)) = -2/8 = -1/4 = -0.25. This is closest to answer choice E) -5.
