Question 344521: Graph this rational function. Start by combining all terms over a common denominator.
2 28 16
_ + _ + __ = fx

3 3x x2
or
2/3 + 28/3x + 16/x2
So
46
_________

x2 + 3x + 3 ??
then would you make x = 1 and solve for fx? then x = 2 solve for fx

common denominator.
2 28 16
_ + _ + __ = fx

3 3x x2


least common multiple (3,3x,x^2)=3x^2, this is the common denominator :

2x^2+28x+3*16
-------------=f(x)
3x^2


x=1, f(x=1)=(2+28+48)/3=78/3=26
f(2)=(2*4+56+48)/12=56*2/12=56/12=28/6=14/3
