Step-by-step explanation:

we are given a function and the inputs (x)

so we just need to substitute the values of inputs (x) to the function and simplify

our given function:

$\displaystyle \: f(x) = \frac{x}{2} - 1$

when x is -2 then

$\displaystyle \: f( - 2) = \frac{ - 2}{2} - 1$

simplify division:

$\displaystyle \: f( - 2) = - 1 - 1$

simplify subtraction:

$\displaystyle \: f( - 2) = - 2$

when x is 0 then

$\displaystyle \: f(0) = \frac{0}{2} - 1$

simplify division:

$\displaystyle \: f(0) = 0 - 1$

simplify substraction:

$\displaystyle \: f(0) = - 1$

when x is 4 then

$\displaystyle \: f(4) = \frac{4}{2} - 1$

simplify division:

$\displaystyle \: f(4) = 2 - 1$

simplify subtraction:

$\displaystyle \: f(4) = 1$

when x is 8 then

$\displaystyle \: f(8) = \frac{8}{2} - 1$

simplify division

$\displaystyle \: f(8) = 4 - 1$

simplify subtraction:

$\displaystyle \: f(8) = 3$
