The average rate of change in a function from a to b is
.
For the left function, from x = 4 to x = 5, the rate of change is
.
For the right function, the rate of change is
![\frac{1024-256}{5-4} = \frac{768}{1} = 768](https://tex.z-dn.net/?f=%20%5Cfrac%7B1024-256%7D%7B5-4%7D%20%3D%20%5Cfrac%7B768%7D%7B1%7D%20%3D%20768%20)
Using a ratio to compare the right function's growth rate with that of the left function, you get
.
The right function is growing approximately 21 times faster than the left function (over the interval from 4 to 5).
1. Consider the transformation that maps the graph of the function
into the graph of the function
This transmormation has a rule:
(x,y)→(x+2,y)
that is translation 2 units to the right.
2. Consider the transformation that maps the graph of the function
into the graph of the function
This transformation has a rule:
(x,y)→(x,y+3)
that is translation 3 units up.
Answer: correct choice is C.
