On the X axis, we consider points A, B and H of respective abscissas 3, -3 and x (x belongs R)

 

Or C the point of Cf of the same abscissa as A and M the point of Cf of abscissa x

 

 

1°) Make the complete figure ?

 

2°) Calculate the distances AH and MH according to x and by means of the absolute values ?

 

3°) To determine for which value (s) of x the areas of triangles CHA and MOB is equal ?

 

 

Please Anyone for help me, Can you draw this graphic please please and represents all points A B H M and C
