$100 is borrowed at 9% interest per year. How much is owed after one year if interest is compounded : a. annually?
b. monthly?
c. continuously?

Step-by-step explanation:

a). Formula to be used,

   A = P(1 + i)ⁿ

       = 100(1 + 0.09)¹

       = $109

b). Formula to be used,

   A =

       =

       =

       = 100 × 1.0938

       = $109.38

(c). Formula to be used,

     A =

         =

         =

         = $109.42

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
