Give the equation of the axis of symmetry and the coordinates of the vertex of the graph of y=x^2+4x+3. Sketch the graph.
Answer by rothauserc(4718) (Show Source): You can put this solution on YOUR website!
axis of symmetry is x = -b/2a = -4/2 = -2
now substitute -2 for x in the given equation
y = (-2)^2 +4*(-2) +3 = -1
coordinates of vertex are (-2, -1)
here is the graph
