A function is matched below against an interval where it is supposed to be increasing. Which of the following parts is incorrectly matched? Interval, Function [2, `oo)` , `2x^3-3x^2-12 x+6` `(-oo,oo)` , `x^3=3x^2+3x+3` `(-oo-4)` , `x^3+6x^2+6` `(-oo,1/3)` , `3x^2-2x+1`

`{:("","interval","Function"),((a),(-oo,-4],f(x)=x^3+6x^2+6):}`

`{:("","interval","Function"),((a),(-oo,1//3],g(x)=3x^3-2x+1):}`

`{:("","interval","Function"),((a),(2,oo],h(x)=2x^3-3x^2+12x+6):}`

`{:("","interval","Function"),((a),(-oo,oo],q(x)=x^3-3x^2+3x+3):}`
