Answer:
Show work in this space
b)What is the line of symmetry?
Answer:
c)Graph the function using the equation in part a. Explain why it is not necessary to plot points to graph when using y = a (x – h)² + k.

)Graph the function using the equation in part a. Explain why it is not necessary to plot points to graph when using y = a (x – h)² + k.
You have the value to determine, Latus Rectum, and direction of opening. Also, vertex form tells you the vertex (h,k).
d)In your own words, describe how this graph compares to the graph of y = x²?
They both are vertical parabolas, and they open upward.
