Explanation:
#"the average rate of change of a function f(x) "#
#"is the slope of the "color(blue)"secant line"" joining the points"#
#(a,f(a))" and "(b,f(b))#
#"here "[a,b]=[0,2]#
#m=(f(b)-f(a))/(b-a)#
#color(white)(m)=(4-2)/2=1#
#"this means that the average of all the slopes of tangents"#
#"to the graph of f(x) between "(0,2)" and "(2,4)" is 1"#
