Determine the end behavior of p. p(x) = 4x3 − x2 + 3x + 6 y → as x → ∞ y → as x → −∞

Y -> infinity as x -> infinity

y -> negative infinity as x -> negative infinity. 

This is because odd powers start down and finish up unless they are negative, which in that case they are opposites. 

The correct answer is $90
