Hope you understand this! :DPart a) section A<span><span>f<span>avg</span></span>=<span><span>4(2<span>)2</span>−4(2<span>)1</span></span><span>2−1</span></span>=8</span>section B <span><span>f<span>avg</span></span>=<span><span>4(2<span>)4</span>−4(2<span>)3</span></span><span>4−3</span></span>=32</span> Part b) The rate of change is greater between x = 3 and x = 4 than between x = 2 and x =1 because an exponential function's rate of change is increasing, unlike a linear function which has a constant rate of change.
