|-4b - 8| + |1 - b^2| + 2b^2 = 27

For b = 2

Step-by-step explanation:

The correct expression is:

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

Required

Evaluate the expression for b = 2

Substitute 2 for b in |-4b - 8| + |1 - b^2| + 2b^2

|-4(2) - 8| + |1 - (2)^2| + 2(2)^2

Open all brackets

|-4*2 - 8| + |1 - 2*2| + 2*2*2

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

Evaluate all expressions in the absolute value brackets

|-16| + |-3| + 8

In absolute values:

|-a| = a

So, we have:

16 + 3 + 8

Hence:

|-4b - 8| + |1 - b^2| + 2b^2 = 27

For b = 2

No, because no association means there is no relationship between the variables. So there is no pattern that results in reliable predictions.
