How would the graph y=|x^2| look like and in q4 how would i draw the second graph?
2. The curve y=x^2 is below the x axis when -2<x<2. The curve y=|x^2-4| is reflected in the x axis between -2<x<2 so between -2<x<2 the curve y=|x^2-4| becomes y=4-x^2.
If x<-2 or x>2 then the curve y=|x^2-4| is simply y=x^2-4.

so is it going to cross (-2,0) (0,4) and (2,0)
