Question 166174: I have two questions.
1. Identify the vertex, axis of symmetry, and direction of opening for y=2(x+3)^2-5
On this I know that the direction of opening is up. That's all I know though. Please help!!!
2. Write y=-4x^2+8x-1 in vertex form.
PLEASE HELP!!!
I must show my work and I am lost on how to do these. We have no text book to help us. This is from a worksheet.
Thanks
