Answer 2

Answer: 2

Step-by-step explanation:

The question is asking you to substitute the b with 4 and find the solution to the expression.

$\frac{1}{2}b^{2} -6$

$=\frac{1}{2}(4)^{2} -6$

$=\frac{1}{2}(16) -6$ (PEMDAS so you do the exponent first)

$=8 -6$ (PEMDAS so you do the multiplication first)

$=2$
