week 14- pre calc 11

This week in pre calc 11 we learned how to determine the difference between and absolute value graph and reciprocal value graph.

we know that an absolute value graph cannot have any negatives at all because when a number is in the absolute value symbol even if it is negative it must change to positive, that’s one way we can tell it is an absolute value graph, another way is that it will make a V shape if it is linear

ex:

and if it’s a quadratic function graph it will make a W shape

ex:

that is unless it is a horizontal line.

 

To tell if it is a reciprical you will notice that it will go in the negatives in most cases

ex:
