EMERGENCY! Please give me the correct answer!

Find the vertex of the function given below y=x^2-6x+1

Use the function f(x) is graphed below. the graph of the function to find, f(6). -2 -1 1 2

Mary beth used the mapping rule to find the coordinates of a point that had been rotated 90° counterclockwise around the origin. examine the steps to determine whether she made an error. m (3, –6) is rotated 90° counterclockwise. (x, y) → (–y, x) 1. switch the x- and y-coordinates: (6, –3) 2. multiply the new x-coordinate by –1: (6(–1), –3) 3. simplify: (–6, –3) .
