4) What happens to our balloon when we subtract a
negative number (sandbags)?

if we add sandbags it will make the balloon sink

if we subtract sandbags it will make the balloon rise

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

y=1/4x-4
