Given exponential function:
Let us obtain three points including the y-intercept so that we can plot the function y = f(x)
When x =0:
when x =1:
when x =2:
We have the points : (0, 1), (1, 1/5), and (2, 1/25)
Using these points, let us provide a sketch of the plot of y =f(x). We have the plot as shown below:
First note that 
; otherwise 
is undefined as long as we're only looking for real solutions.
We can write

A rational number is a number that can be written in form a/b where a and b are integers and b is not eual to 0
simplify eacy
we get
