The oracle function f(:1:) is presented below. For each :1: value you enter the oracle will tell you the value at). Calculate the derivative of the function at 1.3 using the Newton quotient definition. f'(2:) at 1.3 : You can use a calculator x f(x) 1.3 -f> 9.812000000000221 0 --f--> 3.0000000000000133 1.3 --f--> 5.651999999999998 Remember the technique for finding instantaneous velocities from average velocities? This is the same thing
