Determine whether the conclusion is valid. If not, identify the additional information needed to make it valid. Given: JM¯¯¯¯¯≅KL¯¯¯¯¯, JK¯¯¯¯¯≅ML¯¯¯¯¯¯
Conclusion: JKLM is a rectangle.

Conclusion is invalid.

Step-by-step explanation:

Here it is given JM≅KL and JK≅ML. It means the opposite sides are congruent.

It does not given the angles are right angle to conclude it is rectangle.

It can be parallelogram.

So, conclusion is invalid.

step-by-step explanation:

yes because there is exactly one y value for every x value

for function there can't be more than one value for every x value
