What is the distance from X to Y?

X = (0,6)
Y = (9,6)

A. 21 units

B. 15 units

C. 3 units

D. 225 units

Step-by-step explanation:

To find the distance between two points, and , you can use the following distance formula:

Plugging in the points from the problem, you'll get the following:

f(x) = x^3 -2x^2 -3x

x( x^2 -2x-3)

x( x^2 +x -3x -3)

x( x(x+1) -3(x+1))

x( x-3)( x+1)

so zeroes are 0, 3,-1
