Exponential functions have a horizontal asymptote. The equation of the horizontal asymptote is
y=0.
Answer:
Both the equation and its inverse are functions.
Step-by-step explanation:
In order to solve this problem lets first find the inverse of this function. This is done below:

We first swap x and y.

We now isolate y.

Functions are relations between two groups of numbers, in such a way that one number on the input group must generate a singular answer from the output group. This holds true for both f(x) and its inverse, therefore both are functions.
A)The angles are neither complementary nor supplementary.
Complementary- Two angles whose sum add up to 90° ( a right angle)
Supplementary-Two angels whose sum when added together is 180°
It seems to be a obtuse angle - more than 90° but less than 180°
I think the answer would be "I spent 4 hours teaching lessons".
