Answer:
c. 120
Step-by-step explanation:
The factor from the provided expression of the variable x and y is taken out. The resultant expression is -1/4(2x-5y).
<h3>What is a factor of equation?</h3>
The factor of a equation is the terms or number which is common in all the terms of the that equation.
The first term of the equation is,
-1/2x
Multiply with 2 in numerator and denominator of this term as,
-2/4x
(-1/4)2x
Now the second term of the equation is,
-5/4y
Rewrite this term as,
(-1/4)5y
Thus, the expression become,
1/2x - 5/4y
(-1/4)2x- (-1/4)5y
-1/4(2x-5y)
Hence, the factor from the provided expression of the variable x and y is taken out. The resultant expression is -1/4(2x-5y).

Given:
The function is
![f(x)=4(\sqrt[3]{81})^x](https://tex.z-dn.net/?f=f%28x%29%3D4%28%5Csqrt%5B3%5D%7B81%7D%29%5Ex)
To find:
The domain and range of the given function.
Solution:
Domain is the set of input values.
Range is the set of output values.
We have,
It is an exponential growth function, where the initial value is 4 and the growth factor is ![(\sqrt[3]{81})](https://tex.z-dn.net/?f=%28%5Csqrt%5B3%5D%7B81%7D%29)
.
We know that the exponential function is defined for all real values of x. so,
Domain = { x | x is a real number}
In the given function 4>0 and ![(\sqrt[3]{81})^x>0](https://tex.z-dn.net/?f=%28%5Csqrt%5B3%5D%7B81%7D%29%5Ex%3E0)
for all real values of x. So,
Range = {y | y > 0}
Therefore, the correct option is A.
