Given that f(x)=x^2-2x-63f(x)=x 2
−2x−63 and g(x)=x+7g(x)=x+7, find (f-g)(x)(f−g)(x) and express the result in standard form.

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?

If f(x)=-x^2+6x-1 and g(x)=3x^2-4x-1,find(f+g)(x)
