WILL MARK BRAINLIEST How would I be able to graph f(x) = (2x-1)(2x-5)? I just need to know the steps how to.
Korolek [52]

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

Hope this helps!
