Determine the constants a and b in the equation of the curve y = art + be + ex + d having a critical point at (0, -1) and an inflection point at (-1, 2). O a =0;b=-1 O a = 0 ; b=0 O None of the choices O a = -3;b=-6An object was thrown vertically with an initial velocity of 9.9 m/s from a height of 3.0 m. What maximum height did the object reach? Hint: The kinematic function of position is: * = co + vot + ogt where g =-9.80665 m/s2.
