Answer:
Find the "zeros" and plug in points
Step-by-step explanation:
You can tell this graph is a parabola.
We can find the "zeros" of the graph to help us.
Find the zeros:
2x-1=0
2x=1
x=0.5
2x-5=0
2x=5
x=2.5
We can substitute values into f(x)=(2x-1)(2x-5) to graph.
You should get (1.5,-4) to be the vertex.
Hope this helps
