I assume you mean 4(3^x) as in this is an exponential function.

The average rate of change is simply the change in y divided by the change in x so:

(4(3^2-3^1))/(2-1)

4(9-3)

4(6)

24

....

(4(3^4-3^3))/(4-3)

4(81-27)

4(54)

216

So the average rate from 3 to 4 is 216 and from 1 to 2 is only 24.

So the average rate of B to A is 216/24=9, is 9 times greater than A.

The average rate of change is not constant as this is an exponential function.

The value of y varies directly with x. If x = 6, then y = 72 . What is the value of x when y = 108 ?
Ann [662]

Answer:

Hi there!

Your answer is:

x= 9 when y= 108

Step-by-step explanation:

x= 6 when y=72

/72

x = 1/12 when y =1

<em>So</em><em>:</em>

x= _ when y = 108

x= 1/12 when y =1

×108

x= 9 when y= 108

Hope this helps!
