You can check that the limit comes in an undefined form:
In these cases, we can use de l'Hospital rule, and evaluate the limit of the ratio of the derivatives. We have:
and
So, we have

Answer:
Yes, f(x) = is a constant function.
Step-by-step explanation:
A function is defined to be a relation from 1 set of numbers to another set of numbers.
The main condition for a relation to be a function is that for every number in the domain there should be a <u>unique image</u>
Here the given function is f(x) =
This function is a constant function and gives the value 0.75 for all values of x.
Hence the graph would be a straight line parallel to the x-axis passing through y = 0.75.
Hence the f(x) = 0.75 is a function.
