find the bound on the real zeros of the polynomial function
f(x)=x^4+x^34x6
cna you please show me how you got the answer please

you can use the synthetic division to find the smallest k such that (xk) causes all the values in the bottom line to be positive.
Or, to provide an easier (but rougher) bound, see
