Which set of ordered pairs represents a function? \{(9, 4), (-1, 2), (-3, 3), (-1, -6)\}{(9,4),(−1,2),(−3,3),(−1,−6)} \{(-7, 4), (7, 2), (1, 2), (-4, -4)\}{(−7,4),(7,2),(1,2),(−4,−4)} \{(-8, 4), (-8, 1), (0, -1), (5, -6)\}{(−8,4),(−8,1),(0,−1),(5,−6)} \{(-9, -8), (2, -4), (-9, 8), (0, -4)\}{(−9,−8),(2,−4),(−9,8),(0,−4)}

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)

step-by-step explanation:

22 dimes and 9 nickels

step-by-step explanation:

the function makes a strait line horizontally with no x intercept but a y intercept at 9.
