Answer:
0=2(x-1)^2
Step-by-step explanation:
We can determine how many solutions a graph has by how many times it touches the x axis, or the horizontal axis.
The first graph doesn't touch the x axis, therefore it has no real solutions.
The second graph touches the x axis twice, so it has 2 solutions.
The third graph touches the x axis twice, so it has 2 solutions.
The fourth graph touches the x axis once, so it has 1 solution.
Therefore, the graph 0=2(x-1)^2 has 1 real solution.
