(Question 24)

In the plane rectangular coordinate system xOy, the analytical formula of parabola is y =+1,

The coordinates of point C are (–4,0), and vertices A and B of parallelogram OABC are parabolas.

On a straight line, the AB and Y axes intersect at point M, and point Q(x, y) is known to be on a parabola, while point

P(t, 0) is on the x axis.

(1) Write the coordinates of point m;

(2) When the quadrilateral CMQP is a trapezoid with MQ and PC as the waist.

① Find the resolution function of T about X and the range of independent variable X;

② When the ratio of the lengths of the two base sides of the trapezoid CMQP is 1: 2, find the value of t. 。

Is that a problem?
