Rate of Change WITHOUT derivatives PROBLEM: Given f(x]=.i]4[8xx2] Find the rate of change of elevation when x = 2m taking a derivatives directlv. Instead use find the slope between H2 _ 3) and .\"2 + 17) Ex = 1 Find the appropriate 2+x ) and fZ-x ) to nd the slope between two DIFFERENT POINTS closer to the x=2 value. CHALLENGE: ll-'lanvr students each using differentx values seem to be getting verv close to the same answer. Whv is that true? Would it be true for an'glIr function
