Determine if a polynomial function (please show work):
f(x)=5+2x^2-3x^4-2x-x^3

You move the constant to the right side and change its sign to be 9z= -6 -8. that’s the first step.the second step would be calculate the difference of -8-6 to get -14. you equation should now be 9z=-14the last step is to divide both sides by 9 to get z=-14/9hope this

That we do not know what the cost is bro
