Question 909121
{{{f(x)=x^2-2x}}}


{{{f(3)=(3)^2-2(3)}}}


{{{f(3)=3}}}


------------------


{{{f(x)=x^2-2x}}}


{{{f(6)=(6)^2-2(6)}}}


{{{f(6)=24}}}


------------------


Let m be the average rate of change from x1 to x2.


{{{m = (f(x2)-f(x1))/(x2-x1)}}}


{{{m = (f(6)-f(3))/(6-3)}}}


{{{m = (24-3)/(6-3)}}}


{{{m = (21)/(3)}}}


{{{m = 7}}}


The final answer is <font color="red">7</font>
