 Question 355614: Determine the equation of the line that passes through the points of intersection of the quadratic function f(x) = x^2 - 4 and G(x) = -3x^2 +2x +8Answer by edjones(7569)   (Show Source): You can put this solution on YOUR website!We let the equations y coordinates be equal. x^2-4=-3x^2+2x+8 -4x^2+2x+12=0 x=-1.5, x=2 Quadratic formula. To find the y coordinate we can use either of the original equations. x^2-4 =(-1.5)^2-4 =2.25-4 =-1.75 . 2^2-4=0 . (-1.5, -1.75), (2, 0) the 2 points of intersection. . Ed .
