Question 1 (1 point)
Which equation can be represented by a graph with a vertex at (1,3)?

See explanation

Step-by-step explanation:

You have not provided the options to help us give you a specific answer.

If a quadratic function is written in the form

Then (h,k) is the vertex, and 'a' is a constant.

For instance

has vertex at (2,3).

Also, an absolute function in the form

has vertex at (h,k).

This means

also has vertex at (1,3).

I hope this explanation is helpful.
