In Problems 19 and 20, find the quadratic function for which:19. Vertex is (2, −4); y-intercept is −1620. Vertex is ( - 1, 2); contains the point (1, 6)

If h(x) = 4x – 3, what is an equation for h-1(x)? A. h-1(x) = 3x + 4 B. h-1(x) = 3x – 4 C. h-1) = x+ 3 4 h-1Q = x - 3

If the equation ax + 2hxy + by + 2gx+ 2 fy +c = 0 represents two straight lines, %3D find the square of the distance of their point of intersection from the origin. [Here you will choose numeric values of a, h, b, g, f, c as your choice like 2.x? + 6.xy +5y + 4x +3y+2 0but not exactly this].
