OK trying again.
For what (numerical) of the constant "c" is the function
f(x)= {x^2cx if x is greater than 1
{cx^3+x if x is less than or equal to 1
continuous on ( infinity, +infinity)?(Justify answer!)

Calculus 
drwls,
To make the pieces of the function continous at 1, require that the two functions are equal at x = 1
1 + c = c 1
2c = 2
c = 1
