When f(x) = –3, what is x?

–29
–10
–3
–1

x = - 1

Step-by-step explanation:

Locate f(x) = - 3 on the right column of the table with the corresponding value of x on the left column.

Thus f(x) = - 3 when x = - 1 or f(- 1) = - 3

what is the question here

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)
