I'm missing a step somewhere.(adsbygoogle = window.adsbygoogle || []).push({});

Without a calculator, graph y=3x^2-16x-12 by factoring and plotting zeros.

I have gotten as far as (x=-2/3) & (x=6) and know it's a parabola and pointing up because it has the positive x^2 so the graphing is easy enough, except...

The botb says the y-int is -100/3 but I can't find the bridge to get there in my notes or in the chapter.

a hint, please.

Thank you.
