Question

Can anyone help me with these two true/false questions? :)

Answer 1

Answer:

  9.  b. sometimes true

  10.  a. always true

Explanation:

9. Any function will have an inverse relation. This question is not specific as to whether that inverse relation must be a function. We will assume that that is the intent.

The attached graph shows a cubic function with an inverse function (green), and another without (red).

A cubic function will have an inverse function sometimes.

____

10. As stated above, any function will have an inverse relation.

A linear function will have an inverse relation always.

The graph shows a linear function with an inverse function (green), and one that has an inverse relation, but not an inverse function (red).
