Can someone help me and tell me the steps plzz

A

Step-by-step explanation:

f(x) = 7x² - 15x + 2

A) f(1) = 7*1² - 15*1 +2 = - 6

f(1.5) = 7*(1.5)² -15*1.5 + 2 = - 4.75

B) f(2.2) = 7*(2.2)²-15*(2.2)+2 = 2.28

C) f(1) = 7*1² - 15*1 +2 = - 6

f(1) = 7*2² - 15*2 +2 = 0

D) not for all real numbers because we already have

f(2.2) = 7*(2.2)²-15*(2.2)+2 = 2.28 that is positive.

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.
