Answer:
The domain is all real numbers.
The initial value is 3
The simplified base is 
Step-by-step explanation:
The given function is
.
To find the initial value, we put x=0 into the function:
.
.
The initial value is actually 3.
The given function is an exponential function, therefore the domain is all real numbers.
The range of this function refers to all values of y for which the function is defined.
The line y=0, is the horizontal asymptote.
The range is 
The simplified base is
.



Answer:

Step-by-step explanation:
Simplify both of the fractions so
to get 0.93 and
to get 0.57.
Then you put them back into fraction form.
X = 7 / sin(45)
x = 7 / sqrt(2)/2
x = 7 sqrt(2)
