PLEASE HELP ME WITH THESE 3 QUESTIONS YOU GUYS! YOU WILL EARN ALOT OF POINT I PROMISE! 15+ PTS


1) Write a real world situation for the function f(x)=3(1.06^x)+2. Be sure to identify all key features of the function as what they represent in your situation.

2) In a paragraph, compare and contrast constant rate of change and average rate of change.

3) What is the average rate of change of the function g(x)=3(2^x)-6 over the interval 0<=x<=3? Show all work.

Respuesta :

1) not sure of an example but it will be something with exponential growth.

2)  Constant rate of change means the slope is the same between every point (always represented by a straight line).  Average rate of change is the slope between the first and last point (not usually represented by a straight line).

3) g(x) = 3(2ˣ) - 6

g(0) = 3(2°) - 6   = 3(1) - 6   = 3 - 6   = -3      ⇒ coordinate (0, -3)

g(3) = 3(2³) - 6   = 3(8) - 6  = 24 - 6  = 18     ⇒ coordinate (3, 18)

average rate of change (slope) from x = 0 to x = 3: [tex]\frac{y2 - y1}{x2 - x1}[/tex]

  [tex]\frac{18 - (-3)}{3 - 0}[/tex]

= [tex]\frac{21}{3}[/tex]

= 7
