Answer:
B. f(x)=x³+x²-x-1
Step-by-step explanation:
The value of the graph f(x) shows that at x=1 and x=-1 must yield f(x)=0
which is true in case B.
A. f(1)=1+1-4-4= -6≠0
C. f(1)= 1+3-4-12=-12≠0
D. f(-1)= -1+2+2-1= 2≠0
Hence, option B is correct
i.e. f(x)= x³+x²-x-1

Answer:
1110
Step-by-step explanation:
Answer:
a. 16
Step-by-step explanation:
area of a triangle=1/2(bh). In this case, b=10 and h=3 1/5
multiply 10 and 3 1/5 to get 32
multiply 32 by 1/2 to get 16.
