Answer:
C
Step-by-step 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.
