What is the average rate of change of the function on the interval from x = 1 to x = 2? f(x)=10(5.5)x enter your answer, as a decimal, in the box.

Hey there, Rileydavidson18!

To find the rate of change when x = 1 and when x = 2, we need to find the values of the f(x) when x is equal to 1 and 2.

f(x)=10 (5.5)^x

Now, to find the rate of change we need to use the formula 
So, it should be  which would give you  which is the same as 247.5
So, the rate for the interval [1,2] is equal to 247.5

Thank you for using .
See you soon!
