Analysis because P is the intersection of two functions, and the coordinates of point P satisfy two functions, it is known that the ordinate of point P is 1, that is, y= 1, and x=-3 is obtained by bringing it into the inverse proportional function, so p(-3, 1).
Because both functions pass through this point, the solution of the required function is to satisfy this equation. You can subtract the inverse proportional function from the quadratic function, from left to left, from right to right, and then move the term to get the required equation. Then naturally its solution is the abscissa of point p,
In fact, his essence is that you combine these two equations to form an equation set, bring it in to solve it, and then find X, that is, the intersection of the two functions.
