f(-2) means inserting 'x = -2' into the equation.

x = -2

4*|-2 -4| +2

= 4*|-8| + 2

= 4*8 + 2

= 32 + 2

= 34

$\text{The formula of the midpoint of segment AB:}\\\\\left(\dfrac{x_A+x_B}{2};\ \dfrac{y_A+y_B}{2}\right).\\\\\text{We have the points}\ E(-12,\ 5)\ \text{and}\ F(7,\ -9).\ \text{Substitute:}\\\\x=\dfrac{-12+7}{2}=-\dfrac{5}{2}\\\\y=\dfrac{5+(-9)}{2}=\dfrac{-4}{2}=-2\\\\\ \boxed{\left(-\dfrac{5}{2};\ -2\right)}$
