Find the axis of symmerty for x y=x squared -4x-8

Talia grouped the terms and factored out the gcf of the groups of the polynomial 15x2 – 3x – 20x + 4. her work is shown below. (15x2 – 3x) + (–20x + 4) 3x(5x – 1) + 4(–5x + 1) talia noticed that she does not have a common factor. what should she do?

What is the approximate value of the correlation coefficient for the given graph? a. 1 b. 5 c. 3 d. -1
