Zeros: x = 2, x = 4

Turning point: (halfway between the zeros) x = 3, y = -1

y-intercept: where x=0, at f(0) = 8.

Axis of symmetry: the vertical line through the turning point: x = 3.

Step-by-step explanation:

2 of a white ball =2/30 =1/15;

This is the probability of picking a black ball.

Let the number of black ball be X

x/(x +20)= 1/15[ probability of picking black ball ]

15x = x + 20 ; by cross multiplication

14x=20; x = 20/ 14 =1.42 = 1 [ approximately]

But to satisfy the premise given above; we have to approximate the no of balls to 2
