Cuál es el resultado de 10:2+5×3+4×2-16:4-​

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

yes because there is exactly one y value for every x value

for function there can't be more than one value for every x value
