Answer:
Domain (0, ∞) and Range (-∞, ∞).
Step-by-step explanation:
The domain of f(x) = 0.5^x is all values of x and the range is f(x)>0 as 0.5^x cannot be negative or zero.
In interval form this is Domain is (-∞, ∞) and Range is (0, ∞).
So its inverse has Domain (0, ∞) and Range (-∞, ∞).
Let x represent the cost of the movie ticket and y represent the cost of a snack item.
3x + 3y
504÷1800=0.28
28% of her income goes to her rent
We can rewrite the expression under the radical as
then taking the fourth root, we get
![\sqrt[4]{\left(\dfrac32a^2b^3c^4\right)^4}=\left|\dfrac32a^2b^3c^4\right|](https://tex.z-dn.net/?f=%5Csqrt%5B4%5D%7B%5Cleft%28%5Cdfrac32a%5E2b%5E3c%5E4%5Cright%29%5E4%7D%3D%5Cleft%7C%5Cdfrac32a%5E2b%5E3c%5E4%5Cright%7C)
Why the absolute value? It's for the same reason that
since both 
and 
return the same number , and 
captures both possibilities. From here, we have
The absolute values disappear on all but the 
term because all of 
, 
and 
are positive, while 
could potentially be negative. So we end up with
