Can anyone me with these two true/false questions? : ) 9. determine whether the statement is always, sometimes, or never true. a cubic function has an inverse. a. always true b. sometimes true c. never true 10. determine whether the statement is always, sometimes, or never true. a linear function has an inverse relation. a. always true b. sometimes true c. never true ! ,

  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).
