The first graph is a parabola. Since it opens downwards, it means the leading coefficient is negative.
The third graph is also a parabola. Since it opens upwards, it means it has a positive leading coefficient.
The second and fourth graphs represents a polynomial with an odd degree. Since both polynomial goes rises on the left and keeps rising on the right, their leading coefficients are positive.
The correct options are:
B, C , and D
