By completing the square, find any turning points and intersects with the x and y axes of the following curve. f(x) = 2x^2 - 12x +7

f(x) = 2x 2 - 12x +7 First take out a factor of 2 so that we have the coefficient of x 2 as 1. f(x) = 2[x 2 - 6x +7/2] Next, complete the sqaure on the part in square brackets. f(x) = 2[(x - 3) 2 - 9 + 7/2] ...
