(b)
(d)
S.

Answer 2

Answer:

c. q=0

Step-by-step explanation:

cubic equation

the graph contains a local minima and a maxima.

the three roots of cubic polynominal is two negative and one positive.

a quadratic equation has just one root whereas a biquadratic equation has four roots.

moreover for a bi quadratic equation the derivatives is zero at three different places that is direction in which graph opens changes thrice.

all these observations that the roller coaster is represented by a cubic graph.
