# Thread: Function and Geometry [Eleventh Grade] Homework Help

1. The function defined on R by f(x)= (2/3)x+2

And cf his graphic representation in an orthonormal mark (o; i; j)

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  2.

3. Is cf the name of a line between points c and f?

I don't understand this part of your statement: Originally Posted by shawqidu19

Would an orthonormal mark be a position where two lines intersect? If so, then would (o; i; j) be a coordinate set in 3 dimensional space?

In this statement: Originally Posted by shawqidu19

would this mean that we have three lines, y=3, y=-3, y=x where x is a constant?

The way this is written seems confusing to me.  Bookmarks
