Hi! what is y = x^2 -4x +5 vertex form? explain how you got this answer. : )

Given the box plot, will the mean or the median provide a better description of the center? box plot with min at 10.5, q1 at 11.5, median at 12.5, q3 at 13.5, max at 15

Graph y ≥ -x^2 - 1. click on the graph until the correct graph appears.

What is the simplified form of (3.25x10^3)(7.8x10^6) written in scientific notation?
