Answer:

ans. A

Step-by-step explanation:

f(x)=(x-1)(x+2)(x+3)

y=(x-1)(x+2)(x+3)

y=(x²+x-2)(x+3)

y=x³+4x²+x-6

let x=0

y=x³+4²+x-6

y=0+0+0-6

y=-6

therefore the graph pass thru (0,-6) along y-axis

let y=0

y=(x-1)(x+2)(x+3)

0=(x-1)(x+2)(x+3)

x-1=0

x=1 ; (1,0)

x+2=0

x=-2 ; (-2,0)

x+3=0

x= -3 ; (-3,0)

therefore the graph pass thru (-3,0), (-2,0) and (1,0) along x-axis.

the answer A
