F (x) = - 3x^3-x^2+x-3 identify the end behavior of each polynomial function

end behavior is affect by the exponent and whether its negative or positive

y = y^3 starts negative from - ∞ to 0 the from 0 to + ∞ goes positive

since this equation is negative its switched

-∞ to 0 its positive x>0

0 to + ∞ is negative x<0
