Answer:
The generally accepted standard for “normal” blood pressure is 90/60 to less than120/80. If your blood pressure is consistently lower than 90/60, you have low blood pressure. Blood pressure between 120/80 and 140/90 is still considered normal.

Put the value of p = (-2) in the equation , we get
⇒ - 2 - 2³ - 3 - 2² + 4 - 2³ + 7
⇒ - 2 - 8 - 3 - 4 + 4 - 8 + 7
