For what (numerical) of the constant "c" is the function

f(x)= {x^2-cx if x is greater than -1

{cx^3+x if x is less than or equal to -1

continuous on (- infinity, +infinity)?(Justify answer!)

**drwls**, Sunday, September 16, 2007 at 4:28pmTo 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
