Hello,
A cubic polynomial with -2,1,2 as roots is
f(x)=k*(x+2)(x+1)*(x-2)=k(x²-4)(x+1)=k(x^3+x²-4x-4)
Looking the answers ==>k=1
==>Answer A
Answer:
0.0167
Step-by-step explanation:
divide by 100
Answer:
r^9/r^3 = r^9-3 = r^6
Step-by-step explanation:
Use the y-intercept formula: y=mx+b
Plug in one of the points for x and y
Using that, solve for either x or y

Let's solve ~
Y - intercept of the line is the point where value of x is 0 [ where the line cuts y - axis ]

X - intercept of the line is at the point where value of y is 0
[ where the line cuts x - axis ]
