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
