Answer:
The value of the expression for b=-2 is -9.
Step-by-step explanation:
Consider the provided expression.
[tex]|-4b-8|+|-1-b^3|+2b^3[/tex]
We need to solve the expression for b=-2
Substitute the value of b in the provided expression.
[tex]|-4(-2)-8|+|-1-(-2)^3|+2(-2)^3[/tex]
[tex]|8-8|+|-1-(-8)|+2(-8)[/tex]
[tex]|0|+|-1+8|-16[/tex]
[tex]|0|+|7|-16[/tex]
[tex]7-16[/tex]
[tex]-9[/tex]
Hence, the value of the expression for b=-2 is -9.
