By Amy Feraco
Graph of f(x)=x+1 with domain [-1,2) and f(x)=-x^2+1 with domain {-infinity, -1).

Option A: made using Desmos

Graph of f(x)=x+1 with domain [-1,2] and f(x)=-x^2+1 with domain {-infinity, -1].

Option B: made using Desmos

Graph of f(x)=1/2x+1/2 with domain [-1,3) and f(x)=-x^2+1 with domain {-infinity, -1].

Option C: made using Desmos

Graph of f(x)=1/2x+1/2 with domain [-1,3] and f(x)=-x^2+1 with domain {-infinity, -1].

Option D: made using Desmos

Which of the graphs have the domain of (−∞,2)(-\infty,2) and the range of (−∞,3)(-\infty,3)?
