You have
The domain of a function are its possible input values
The domain of the function is <em>(b) all real numbers greater than or equal to 0.</em>
From the graph, we have the following observations
- <em>t represents time (it is plotted on the x-axis)</em>
- <em>t starts at 0</em>
- <em>t has no end</em>
The above observations imply that; the domain starts from 0
Hence, the domain of the function is the set of all real numbers greater than or equal to 0.

Answer:
20%
Step-by-step explanation:
An equation is 14=x/100*70 or 14=(x%)*70, either one works
solve for x:
- 14=x/100*70
- 14/70=x/100 (Divide each side by 70)
- 1/5=x/100 (Simplify 14/70)
- 100/5=x (Multiply each side by 100 to isolate x)
- x=20 (Simplify 100/5)
- 20% (Rewrite as a percent)
hope this helps!!
no, it is constant for a while then changes at 90gallons
