Write the equation of the axis of symmetry and find the coordinates of the vertex of the graph of each function..Identify the vertex as a maximum or minimum. problem: y=2x^2 + 3
Axis: x = -b/2a = -0/4 = 0
---------
Vertex: (0,f(0)) = (0,3)
--------
Minimum because a=2>0
---------------------------------------
Next problem: graph y = x^2-2x-1
Axis : x = -(-2/2 = 1
---------
Vertex: (1,f(1)) = (1,-2)
----------
y-intercept: f(0) = -1
y-intercept: (0,-1)
---------------
