Find f(3) f(x)=x+2/x
A) -1/3
B)1/3
C)5/3
D)-5/3

 1/3

Work Shown:

f(x) = (x+2)/x

f(-3) = (-3+2)/(-3) replace every x with -3

f(-3) = -1/(-3)

f(-3) = 1/3

The answer would be b ! explanation: the formula for sa *surface area * is 2×l×w+2×l×h+2×w×h so in this case l=4w=12h=8so you use the formula to solve it and it give you the answer of 352^cm^2
