Y=x^{2}+6x+14 in vertex form

Given f(x) = 2x^2- 5x+1, determine the function value f(2). do not f(x) = in your answer

Lindsay used two points, (x,y; ) and (+2.82), to find the equation of the line, y = mx + b, that passes through the points. y2-y, first, she used the definition of slope and determined that the value of mis x, - . given this information, which expression must represent the value of b?
