Document Summary
Example 1: calculate the average rate of change of the given function over the given interval. Where appropriate, specify the units of measurement. a). b). Hint [see example 2. ] (assume a = 12, b = 18, and c = 24. Round your answer to the nearest cent. ) d). Calculate the average rate of change of the given function over the given interval. Hint [see example 1. ] (assume a = 5, b = 11, and c = 17. ) Example 2: calculate the average rate of change of the given function over the given interval. Where appropriate, specify the units of measurement a). (cid:1858)(cid:4666)(cid:4667)=2+4 1; [1,2] b). f(x) = 3x3 + 3 over the interval [5,7] 3 c). (cid:1877)= 4(cid:1876)+1 between x=0 and x=12 d). (cid:1877)=(cid:1857) between x = 2 and x = 4. Another form of the average rate of change: given 2 points: (a, f(a)) and (a +h,f(a +h)). af h af h (think slope formula).
