The value of expression at b= -2 is -11

Step-by-step explanation:

Given: Expression = $\left |-4b-8\right |+\left | -1-b^2\right |+2b^3$

To find: Value of given expression when b = -2

Expression

$\left |-4b-8\right |+\left | -1-b^2\right |+2b^3$

Put, b = -2 in above expression. we get

⇒ $\left |-4\times(-2)-8\right |+\left | -1-(-2)^2\right |+2(-2)^3$

⇒ $\left |8-8\right |+\left | -1-4\right |+2\times(-8)$

⇒ $\left |0\right |+\left | -5\right |+(-16)$

⇒ 0+5-16

⇒ -11

Therefore, The value of expression at b= -2 is -11

B) π

Step-by-step explanation:

The distance between the repetition of any function is called the period of the function. In this case, the period of the parent function y = tan x will have a period of π. This means it takes a distance of π units to complete one cycle of a tangent function.
