Question

Evaluate the expression for the given value of the variable


|-4b - 8| + | -1 -b^2| + 2b^3; b = -2


I will give mark brainliest and all the points I can, please any help means alot, im just really confused >_<


thank you to anyone who helps!!! :)

Answer 1

|-4b-8|=-4(-2)-8=8-8=0

|-1-b^2|= -1-(-2^2)= -1-(4)=-1-4=-5=5( bcoz modulus is there

2b^3=2(-2^3)=2(-8)=-16

--------> 0+5-16=-11

hope it helps you

Answer 2

Given b = -2

|-4b - 8| + | -1 -b^2| + 2b^3

|8 -8 | + |-1 -4| - 16

0 +5 - 16

= -11

since mode function always give positive value
