(08.03) Identify the factors of x2 - 4x – 21. (4 points)
O (x - 7)(x + 3)
O (x + 7)(x - 3)
O (x + 21)(x - 1)
O (x - 21)(x + 1)

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

idk

idk

i know the way

and

idk

hi how are you doing today? if you ever need just tell me

step-by-step explanation:

e^-kt = n/n0 = 0.79  

-kt = ln 0.79  

t = - ln 0.79/0.0001  

= 2357 years
