Range for the given Exponential function 
is f(x) > 0.
the correction option is a). f(x) > 0
The function given in, the question is exponential function is given by
Which is an exponential function. The domain of the give function is (-∞, ∞).
<h3 /><h3>what is exponential function?</h3>
The function which is in format f(x) = 
where, a is constant and x is variable, the domain of this exponential function lies (-∞, ∞).
the Question seems to be incomplete. And options could be
a) f(x) > 0 c) f(x) ≤ 0
b) f(x) < 0 d) f(x) ≥ 0
Simplification of the given equation
clearly, the range of the exponential function is f(x) > 0.

Answer:
The circumference of clock is, 53.38 cm
Step-by-step explanation:
Circumference(C) of the circle is given by:
....[1]
where, r is the radius of the circle.
As per the statement:
the radius of a clock face is 8.5 centimeters
⇒r = 8.5 cm
Use
Substitute the given values in [1] we have;
Simplify:
C = 53.38 cm
Therefore, the circumference of clock is, 53.38 cm
Answer:
The equivalent statement is ![(\sqrt[4]{80})^{x}](https://tex.z-dn.net/?f=%28%5Csqrt%5B4%5D%7B80%7D%29%5E%7Bx%7D)
⇒ 2nd answer
Step-by-step explanation:
* Lets explain how to solve the problem
- Any root can be a fraction power
- Ex: 
![\sqrt[3]{a}=a^{\frac{1}{3}}](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7Ba%7D%3Da%5E%7B%5Cfrac%7B1%7D%7B3%7D%7D)
![\sqrt[4]{a}=a^{\frac{1}{4}}](https://tex.z-dn.net/?f=%5Csqrt%5B4%5D%7Ba%7D%3Da%5E%7B%5Cfrac%7B1%7D%7B4%7D%7D)
![\sqrt[n]{a}=a^{\frac{1}{n}}](https://tex.z-dn.net/?f=%5Csqrt%5Bn%5D%7Ba%7D%3Da%5E%7B%5Cfrac%7B1%7D%7Bn%7D%7D)
* The expression is 
∵ can be written as 
∵ ![(80)^{\frac{1}{4}}=\sqrt[4]{80}](https://tex.z-dn.net/?f=%2880%29%5E%7B%5Cfrac%7B1%7D%7B4%7D%7D%3D%5Csqrt%5B4%5D%7B80%7D)
∴ =
* The equivalent statement is
