As an estimation we are told £3 is €4.
Convert €20 to pounds.

£15

Step-by-step explanation:

=

Cross multiply and solve for x:

4x = 60

x = 15

So, €20 is equal to £15

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
