Answer: -92
Step-by-step explanation:
so first plug in -4 for all the x values.
this is how your equation will look like.
(-4)^(3)-2(-4)^(2)-(-4)
then you cube the -4
(-4)^(3)
then square the -4 and multiply it by -2
-2(-4)^(2)
then multiply the negatives which becomes positive
-(-4)
once you have all that done, you should have this
-64-32+4
finally solve it and you will get your answer as -92
