Find the domain of the funtion 4/x-7
dedylja [7]
Domain means which values the function can have which make it true or Possible to solve

So all you got to do is set the denominator = to 0 and solve for x
You will get x=7

4/(7-7) is not possible

So x cannot equal to 7 because you cant divide a number by 0!

Which are coplanar and noncolinar?
Paul [167]

<em>Coplanar</em> means "lying on the same plane," while <em>colinear </em>means "lying on the same line." In this problem, all four points A, B, C, and D are coplanar - they all lie on the plane \mathcal{H} - so we just need to find the points that lie on the same line. Though points C and B <em>would </em>be colinear if there was a line drawn between them, there's no such line in this problem, so we can rule that out. We notice one line drawn on the plane, and points A, C, and D lying on it, so we can say that points A, C, and D are both coplanar and colinear.
