the first solution is 20% acid, and say we'll be using "x" liters, so how many liters of just acid are in it? well 20% of "x" or namely 0.2x. Likewise for the 60% acid solution, if we had "y" liters of it, the amount of only acid in it is 0.6y.
Find the domain of the graphed function.
2 answers:
For every point on the curve, imagine drawing a vertical line until that vertical line reaches the x axis.
Doing this will essentially shade the x axis number line from x = -4 to x = 2
The graph shows points in which the x coordinate is as small as -4 or as large as 2, or anything in between
Domain:
Answer: Choice B
note: the domain is the set of allowed inputs or x values
