Negative three times a number increased by seven is less than -11

7 or greater

Step-by-step explanation:

Negative three times a number increased by seven is less than -11

So, -3 times x + 7 = >-11

x = 7 or greater

step-by-step explanation: step 3 should really go to step seven, but anyway never mind.

1 ∠oln ≅ ∠lno

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
