The number of private investigators is expected to increase from 25,000 in 2009 to 30,000 in 2019. If there are 312,500 police officers in 2009, how many police
officers must there be in 2019 to have a greater percent increase than that of
private investigators? *

police officers

Step-by-step explanation:

That's a 20% increase.

So increase the police by 20% gets you:

Based on the wording of the question, if you want a greater percentage, the answer should be a single policeman more, thus 375,001.

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
