Question 1189651
<br>
Wrong format -- we don't know what the functions really are.<br>
The sequence of characters "(^" has no meaning.  For example, your case C) you show as<br>
2^(4(^x-1)) +5 <br>
Is that supposed to be<br>
2^(4^(x-1)) +5<br>
or something still different?<br>
Re-post with correctly formatted functions.<br>
