Question 916366


{{{f(x)=3x^-3}}}......this is not a Parabola, it's hyperbola 

{{{f(x)=3(1/x^3)}}}..........


Roots -1 , 1 ...these are not roots

if you need to find and plot points (-1,f(x)) and (1,f(x)), here is how to do it:

{{{f(-1)=3(1/(-1)^3)}}}

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

{{{f(-1)=-3}}}


{{{f(1)=3(1/(1)^3)}}}

{{{f(1)=3(1/1)}}}

{{{f(1)=3}}}

points are: (-1,-3) and (1,3)
