4 2 lesson - graphing in standard form
TRANSCRIPT
Standard Form: y = ax2 + bx + c
X-value of the Vertex: x = -b/2a
Y-intercept: (0,c)
What are the vertex, axis of symmetry, and minimum or maximum of y = 2x2 + 8x – 2?
Graph: y = x2 + 2x +3
Now you try: p.206 #23
What is the vertex form of y = -x2 + 4x – 5?
Now you try: p. 206 #27
