Find the domain of (x, y) → (x + 7, y - 9) with R = {(-3, -14)

Step-by-step explanation:

x+7=-3

x=-3-7=-10

x=-10

y-9=-14

y=-14+9

y=-5

Domain of (x,y)=(-10,-5)

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

its (2) option

answer: b.

step-by-step explanation:

the y coordinate for point b is 0, and answer b is the only one with that y coordinate.
