Given:


In , it's a parabola and follows the form

For the Vertex, ,
Substitute to the Eqn to Y:


The Vertex ----> (1,-2)

We solve the eqn to find the x-Intercepts:


For the Discriminant:

Then,




We see the graph,
--->


In , is a Line with the form .


Let Fy=0
---> ---->
, x-Intercept (5/3,0) = (1.67,0)

Let Fx=0

, y-Intercept (0,5)

--->

Thank you,
