Question

part a-graph the quadratic linear system) y=-x squared-4x+12    and y=-2x+4
-i understand how to do that.
part b) find all the solutions to the system.  <---- i dont understand this, please help!

anonymous · Answer

solution to the system geometrically represent the point of intersection 
you can get the point of intersectn. by simultaneously solving the equation of curves
here,  y= -x^2-4x+12
and, y=-2x+4

-x^2-4x+12=-2x+4
