Solve the following systems of inequalities and select the correct graph:
2x − y > 4 x + y < −1
in each graph, the area for f(x) is shaded and labeled a, the area for g(x) is shaded and labeled b, and the area where they have shading in common is labeled ab.
a dashed line g of x rising left to right that is shaded below and a dashed line f of x that is falling left to right that is shaded above
a dashed line f of x rising left to right that is shaded above and a dashed line that is falling g of x left to right that is shaded above
a dashed line g of x rising left to right that is shaded above and a dashed line f of x that is falling left to right that is shaded below
a dashed line g of x rising left to right that is shaded below and a dashed line f of x that is falling left to right that is shaded below

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)
