Calculate the average rate of change from x = -2
to x = 1 of the function below.
f(x) = x2 + 5x - 12
First, find the change in y by evaluating the
function at -2 and 1.
f(-2) =
f(1) =
The change in y is

idk

step-by-step explanation:

-14 is the answer

hope this : ))

since your problem is x^4 = 81, what you have to undeo is the "to the fourth power" part.

the inverse (opposite operation) of "to the fourth power" is "to the fourth root".

  (x^4) ^ ¼   = 81 ^ ¼  

  81 = 3^4     so (3 ^ 4) ^ ¼   =   3 ^ 1   = 3

by hand: (3 ^ 4) ^ ¼   =   3 ^ (4 x ¼) = 3 ^ 1   = 3   (when you take a power to a power, multiply the exponents.)

or, do it by calculator. one way of finding the fourth root is to use ^ (1/4)
