Describe how to determine Average rate of change between x=4 and x=6 for the function f(x)=2x^3 + 4 Include the average rate of change in your answer.

20 points PLEASE HELP

I know this is all I can give but please someone explain and help me it will mean the world to me。

Triangle xyz, with vertices x(-2, 0), y(-2, -1), and z(-5, -2), undergoes a transformation to form triangle x? y? z? , with vertices x? (4, -2), y? (4, -3), and z? (1, -4). the type of transformation that triangle xyz undergoes is a . triangle x? y? z? then undergoes a transformation to form triangle x? y? z? , with vertices x? (4, 2), y? (4, 3), and z? (1, 4). the type of transformation that triangle x? y? z? undergoes is a .
