What is 845,001 rounded to the nearest hundred thousand

Using the completing-the-square method, find the vertex of the function f(x) = 2x2 − 8x + 6 and indicate whether it is a minimum or a maximum and at what point. maximum at (2, –2) minimum at (2, –2) maximum at (2, 6) minimum at (2, 6)

What are the domain and range of the function? f(x) = -4 (sqrt)x
