How do i do this? i don't really undretsand what i do.

1) (-36)

2) 4

3) (-4)

4) (-20)

5) (-12)

Step-by-step explanation:

See, above it written that y = (-4)x

Then below they are giving the value of x

So, according to that we have to solve the value y

For example:

y = (-4) x 9

y = (-36)

Hope you understood and hope it helps!!!

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

the answer is c hope it
