Modulus and Quadratic functions

Finding roots of quadratic and modulus functions
The task is to investigate how translations affect the roots of quadratic and modulus functions. This geogebra worksheet plots f(x)=(x+p)^2+q and g(x)=|x+r|+s. Some prompt questions are below. How are the graphs similar and how are they different? What values can q take so that the quadratic has at least one root? What is the relationship between p and q (or r and s) and the minima? When do the modulus and the quadratic functions have the same roots? What values of p and q (or r and s) give the root x=0? What about x = 1, 2 or 5? What is the relationship between the sliders and the roots?
