given the function f(x)=4(2)^x, section A is from x=1 to x=2 and section B is from x=3 to x=4 Part A: Find the Average Rate of change of each section Part B: How many times greater is the average rate of change of section B than section A? Explain Why one rate of change is greater than the other.

are you trying to evaluate it
dr0zier99
  • dr0zier99
Substitute the value of the variable into the equation and simplify f(3)=64
dr0zier99
  • dr0zier99
section a: f(x)=4(2)^x 1.......8 2.......16 section b: 3.......32 4.......64
dr0zier99
  • dr0zier99
section b is 4 times greater than section a

if i simplify f(3)=64 I get 0

I think that the definition of average rate \(r\) of change, can be this: \[\Large r = \frac{{f\left( {{x_2}} \right) - f\left( {{x_1}} \right)}}{{{x_2} - {x_1}}}\] where: \[\Large f\left( x \right) = 4 \cdot {2^x}\]

Michele _Laino is that for Part A?
Michele_Laino
  • Michele_Laino
it is for parts A, and B for example, for part A, we can write: \(x_1=1,\,x_2=2\)
anonymous
  • anonymous
oh ok
Michele_Laino
  • Michele_Laino
whereas for part B, we can use the same formula, with \(x_1=3,\,x_2=4\)
dr0zier99
  • dr0zier99
so i was correct when i said that part b was 4 times greater than part a
anonymous
  • anonymous
what about the last part for part b explain why one rate of change is greater than the other?
anonymous
  • anonymous
Yes you were correct when you said that

Thanks for helping guys but I don't know who to give the medal to
dr0zier99
  • dr0zier99
no problem
