(2) explain why there can't be a simple graph with the following sequence of vertex degrees: (a) 5,1,1,1 (b) 4,3,3,1,1,1,1,1

hiking down a winding trail.

step-by-step explanation:

the image is given below

since the options are not given so we draw it from the equation

the given equation is

y = (x-1) (x+4)

y = y² + 3x - 4

the above equation is a quadratic equation which will have two roots. if we draw the graph for it, it will look like this

y - 25 = 2 ( x - 10 ) should be the answer
