• 1. It is known that the image of the first-order function y = 3x + 3 intersects with the x-axis at point a and the y-axis intersects with point B, and the image of the second-order function y = - x ^ 2 + BX + C passes through two points a and B 1) There is a point m on the parabola, so that the area of △ mAb is equal to the area of △ OAB, and the coordinates of point m are obtained 2) On the line AB, there is a point P passing through P, making a parabola at the intersection of L / / X axis and C D (C is on the left side of D).

• 2. I'm preview now! Determine whether the following is a function relation. Y = + - x, y = x & #; When x = 1, y has two corresponding values, so y is not a function of X. when x = 1, - 1, y has a definite value of 1, so it is a functional relationship. So I want to ask, this problem does not tell who is a variable and who is a constant. Then I regard y as a variable, and when y = 1, x = + - 1, there are two corresponding values. Is it not a functional relationship? I'm a sophomore in junior high school. I just preview the new content tonight, Weak ask you big brother ~ swelling? Can only see x?
