check my table! algebra functions?

Question

function , f(x)=-2x^4 
please check over my table i wasnt quite sure if it is correct

Randy P · Accepted Answer

None of those values should be positive.

x^4 is always >= 0.
So -2x^2 will always be <= 0.

In other words, change the sign on the first two values.
