Question

I need help on Number 3

Answer 1

C

Explanation:

x-int is when y=0

when f(x)=0, x=0,-3

A. 0= -x(x-3)

x=0, +3. NOT IT

B. 0= x+(x+3)

2x=-3

x=-3/2. NOT IT

C. 0=x(x+3)

x=0, -3. YESSSSS

D. 0= -x(x+3)

x=0, -3. YESSSSS

Since 0 cannot be neither positive nor negative, both C and D fulfill the first requirement.

but 2nd requirement= f(-1)=-2

C. f(-1)=-1(-1+3)=-1*2=-2 VOILA!!!

C. is the ans.
