Ok so i cant figure this out to save my life, if someone could plz help me try to understand this that would b amazing hrre is the equation
Calculate f(-4) for the function f(x=×2nd +4×_2
f(x) = x^2 + 4 x^-2
= x^2 + 4/x^2 [note x^-2 is simply 1/ positive power)
f(-4) = (-4)^2 + 4/ (-4)^2
=16 + 4/16
=16 + 1/4
=16 1/4 or 16.25
