For something quadratic, you're better off looking at the original graph to determine the pos/neg part. In essentials they graph the whole thing, using a dotted line for the neg part then reflect it in the pos axis - something like that.

Find: y<x^2+4x+4
Is there an actual algebraic answer or just a shaded graph?

I reckon you'd sketch it.

= which is a graph with a minimum of zero. Make sure it's a dotted line graph. Then shade in underneath this graph, to represent 'less than the graph' and have a legend saying shaded area is required region or something like that.

Underneath you mean everything outside the parabola right?
