Last week, an information centre had 950 visitors. This week it had 1026 visitors. What is the percentage increase?

Difference between two weeks = 1026 - 950

Difference between two weeks = 76

Increase in % = Difference/Visitors of last week × 100

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

its (2) option
