The positive interval of a function is when the function has positive values.
<em>The interval in which both f(x) and g(x) are positive is </em>
<em />
<em />
<em />
From the given graphs of g(x), we have the following observations.
- <em>The graph of f(x) crosses the x-axis at </em>
<em /> - <em>The graph of g(x) also crosses the x-axis at </em>
<em>.</em>
<em />
<em />
This means that:
<em />
<em> --- for both functions</em>
But when x increases, the value of y becomes positive,
<em>So, the positive interval of f(x) and g(x) is </em>
<em />

Answer:
2 1/10
Step-by-step explanation:
convert the decimal number to a fraction by placing the decimal number over a power of ten. since there is 1 number to the right of the decimal point, place the decimal number over 10^1 (10). next, add the whole number to the left of the decimal.
hope this helps
ANSWER
![3 {x}^{2} y \sqrt[4]{y}](https://tex.z-dn.net/?f=3%20%7Bx%7D%5E%7B2%7D%20y%20%5Csqrt%5B4%5D%7By%7D%20)
EXPLANATION
We want to simplify:
![\sqrt[4]{81 {x}^{8} {y}^{5} }](https://tex.z-dn.net/?f=%20%5Csqrt%5B4%5D%7B81%20%7Bx%7D%5E%7B8%7D%20%7By%7D%5E%7B5%7D%20%20%7D%20)
We can split the radical sign to obtain:
![\sqrt[4]{81} \times \sqrt[4]{ {x}^{8} } \times \sqrt[4]{ {y}^{5} }](https://tex.z-dn.net/?f=%20%5Csqrt%5B4%5D%7B81%7D%20%20%5Ctimes%20%20%5Csqrt%5B4%5D%7B%20%7Bx%7D%5E%7B8%7D%20%7D%20%20%5Ctimes%20%20%5Csqrt%5B4%5D%7B%20%7By%7D%5E%7B5%7D%20%7D%20)
Or
