Answer:
Step-by-step explanation:
First, we can factor all of the following equations to turn that weird, huge looking thing into ÷
×
. We know that division is simply multiplication by the reciprocal, so that whole equation will turn into
×
×
. Now we can cancel out some values if they are both in the numerator and denominator, which will turn that still huge looking thing into
which is our final answer, as it cannot be simplified further.
Hope this helped! :)

Answer:
f(x) > 0 over the interval
Step-by-step explanation:
If f(x) is a continuous function, and that all the critical points of behavior change are described by the given information, then we can say that the function crossed the x axis to reach a minimum value of -12 at the point x=-2.5, then as x increases it ascends to a maximum value of -3 for x = 0 (which is also its y-axis crossing) and therefore probably a local maximum.
Then the function was above the x axis (larger than zero) from , until it crossed the x axis (becoming then negative) at the point x = -4. So the function was positive (larger than zero) in such interval.
There is no such type of unique assertion regarding the positive or negative value of the function when one extends the interval from to -3, since between the values -4 and -3 the function adopts negative values.

If you meant what you wrote, then we have
If you meant to write (the cube root of 256), then we could go on to have
