Given f(x) = 4x + 1 and g(x) = a, choose
the expression for (fºg)(x).

4x^4 + 1

Step-by-step explanation:

it is same with the question you posted previously

take whole g(x) equation and replace it with the x in the f(x) function

(fog)= 4 ×(x^4) + 1 ➡ 4x^4 +1

center= (-2,0)

radius= sqrt2/2

step-by-step explanation:

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)
