Plot the zeros of the polynomial y = x4 + 3x3 − 27x2 + 13x + 42

See explanation

Step-by-step explanation:

Consider the polynomial 4th power polynomial function has at most 4 zeros.

Integer zeros can be only among the divisors of 42:

Check them:

Thus,

Zeros are plotted in attached diagram.

answer:

the position of equilibrium will shift to the left.

step-by-step explanation:

the general equation for the dissociation of a weak base is

b + h₂o   ⇌   bh⁺ + oh⁻

according to le châtelier's principle, when a stress is applied to a system at equilibrium, the system will respond in a way that tends to relieve the stress.

if you apply a stress by adding more bh⁺ or oh⁻,   the system will respond by moving in a direction that gets rid of the added ions.

the position of equilibrium will shift to the left, forming more of the undissociated base.

y=mx+b is the final answer!   : )
