Can someone explain why the answer is D

a < 0 because it finishes downwards

e < O because the y-intercept is in the negatives.

b, & d = zero (but i don't get this)

c is supposedly > 0 (nor do i get this)

According to the solutions the graph is an even function, and symmetrical about the y-axis/x-axis. I haven't studied this, can someone please explain for values b,d,c.
