If you are approximating, then you are estimating... therefore your answer would be an estimate. I hope this helps.
I am pretty sure that it is just 7. since (-7)^2 is 49 and (-7)^-1 should be 7 and 49/7=7
(you might want to double check with a calculator)
Exactly the same way you would do it if it were a proper fraction . . .
multiply the numerator by the whole number, and then clean up
the fraction.
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 Brainly.
See you soon!
