Differentiate using the exponential rule, which determines that
is
when a=3.

Therefore, the correct option is "E". You just have to remove the parentheses.

Because x is negative the domain of the function is all negative real numbers.
Set the radical greater than or equal to 0:
-x >= 0
Turn x positive by multiplying both sides by -1. When you multiply an inequality by -1 you need to reverse the inequality sign:
X <= 0
Domain is all real numbers below 0 so all negative real numbers.
The chance of a point landing in that region is 12.5%
The answer would be D i believe
The fourth one, (3,-6), (3,-4), (6,-4), (6,-6)
