$49,394.66

Step-by-step explanation:

Use the compound amount formula:

A = P(1 + r)^t

Here A = $65,000; t = 7 years; and r = 0.04.

We want P, given A, r and t.

        $65,000

P =  =  $49,394.66

        (1 + 0.04)^7

$49,394.66 will increase to $65,000 in 7 years with an interest rate of 4% compounded annually.

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
