Answer:
The function is negative for all real values of x where
x < –3 and where x > 1.
Step-by-step explanation:
This quadratic function is downward parabola.
It's root are -3 and 1.
Quadratic is positive between -3 and 1.
And negative on R-(-3,1).
The solutions to this will be found where the graph goes through the x-axis...when y = 0. Since f(x) and "y =" are interchangeable, this makes sense. When you graph it and use your "trace" button you will find that the solutions are -1.8608, -.254102, and 2.11491
(1/4)^3 = 1/64 Hope this helps! Thanks!
