Answer:
domain(-4,6) and range(-1, 8)
Step-by-step explanation:
domain is an imput on x axis, and range on y
What are the two functions?
Notice the picture below
see where that angle is?
check your Unit Circle for that value
also notice, that fractions of

are just like grabbing 180 degrees and splitting it, so one third of 180 or

is 180/3 or 60 degrees
we have the function

we know that
In the equation of the exponential function of the form

a is the initial value
b is the base
x is the exponent
The initial value is the value of the function when the value of x is equal to zero
in this problem
for 


the initial value is the point 
therefore
the answer in the attached figure
