PLEASE HELP I GIVE HIGH HIGH POINTS AND IVE BEEN NEEDING THE ANSWER TO THIS FOR AWHILE A person's systolic blood pressure, which is measured in millimeters of mercury (mm Hg), depends on a person's age, in years. The equation: P = 0.004y2 − 0.02y + 120
gives a person's blood pressure, P at age Y years.
