Question

Please help!!! Don't understand how to solve

Answer 1

So, it looks like all your answers for the axis of symmetry are correct. I'm guessing you only need help on the value of the vertex.

The vertex is the peak of curve of the parabola.

In the first graph y= 3. 
In the second graph, y= -3
In the third graph,  y=3 
In the fourth graph, y= -3

However, I can not see the lines of the graph very well, and these numbers are just what I believe the values to be. Now that you know what the vertex is and the estimated values of y, can you figure out the rest of the problem?
