Yeah it is!
\( \color{Black}{\Rightarrow y^2 + 3x - 4 = 0}\)
Or am I forgetting my Math?
\( \color{Black}{\Rightarrow y^2 = 4 - 3x}\) \( \color{Black}{\Rightarrow y = \sqrt{4 - 3x}}\)
Solve for y. A plot of the result is attached.

F(x) = 3x+1,x<=0 x^2,0<x<4,evaluate f(3) X-5,x>=4
So overall it is a function
