Which function represents g(x), a reflection of f(x) = 4across the x-axis?

g ( x ) = -4 (2) x
g ( x ) = 4 (2) -x
g ( x ) = -4
g ( x ) = 4

The function that represents g(x), a reflection of f(x) = 4 across the x-axis is:

Step-by-step explanation:

We are given a parent function f(x) as:

We know that any function f(x) when is reflecting across the x-axis then the transformed function i.e. g(x) is given by:

Hence, here the transformed  function g(x) that is obtained by transforming f(x) is given by:

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)
