Answer with Step-by-step explanation:
We are given that
![f(x)=log_3(x)](https://tex.z-dn.net/?f=f%28x%29%3Dlog_3%28x%29)
![g(x)=3x](https://tex.z-dn.net/?f=g%28x%29%3D3x)
a.We have to find g(f(x))
![g(f(x))=g(log_3(x))](https://tex.z-dn.net/?f=g%28f%28x%29%29%3Dg%28log_3%28x%29%29)
![g(f(x))=3log_3(x)](https://tex.z-dn.net/?f=g%28f%28x%29%29%3D3log_3%28x%29)
b.We can see that
f(x) is logarithm function and g(x) is linear function.
But , the composition function gof(x) is also logarithmic function.
The composition function gof(x) is 3 times the function f(x).
12.74 divided by 13 is 0.98.

Answer: The total amount the water change was -28 gallons by the end of the week <u>OR</u> The total amount the water changed decreased 28 gallons by the end of the week. Depending on how you want to word it.
Hope this helps!
Step-by-step explanation:
<u>Create you equation:</u>
x = the total amount the water changed
d = the amount of days
x = -4d
<u />
<u>Insert the known information into the equation and solve:</u>
x = -4d
x = -4(7)
x = -28
Answer:
-5x³ -5x² -9x - 4
Step-by-step explanation:
(-6x³-4x²-8)+(x³-x²-9x+4)
Add the like terms.
-6x³ and x³ are like terms. -6x³ + x³ = -5x³
-4x² and -x² are like terms. -4x² - x² = -5x²
-8 and 4 are like terms. -8 + 4 = -4
-6x³-4x²-8 +x³-x²-9x+4 = -5x³ -5x² -9x - 4
