Answer:

x²-4x+5

Explanation:

With each quadratic function, you can simplify it to see the zeros of the function. Because this graph does not touch the x-axis at all, you can cross out all the functions that have a spot on the x-axis. This includes x²-6x+5, -x²-2x+3, x²+4x-5. Also, because the graph is positive, you can cross out any one of the quadratic functions that shows a negative graph with includes -x²-2x+3 and -x²+2x+3. Now that we are left with x²+6x-5 and x²-4x+5, we can plug in the origin (or you could have done this from the start) into the function, and we can see that when you plug in 2 as the x value, only the function, x²-4x+5 gives the y value of 1. Therefore, this is the answer.

Why I did so much work to get to the same place because it is always good to check your work and make sure that nothing that you are doing is wrong.
