Answer:
Domain: All real numbers or (-∞, ∞)
Range: [-9, ∞)
Step-by-step explanation:
Domain is the set of x-values that can be inputted into function f(x).
Range is the set of y-values that can be outputted by the domain.
We can see that you can plug in any x-value into the graph. Therefore, any number would work (All real numbers).
We can also see that are absolute minimum y-value is -9. Therefore, our range is from -9 (included) to infinity.
Answer:

Step-by-step explanation:
— Round tables will have 6 chairs, rectangular tables will have 10 chairs, the total number of chairs must be at least 185: 6x +10y ≥ 185
— There be no more than 15 rectangular tables: y ≤ 15
— No fewer than 6 round tables: x ≥ 6
— Rectangular tables must be at least 1/3 the number of round tables: y ≥ (1/3)x ⇒ 3y ≥ x
It covers approximately a 70% of the Earth's surface, formed by a combination of Hydrogen and Oxygen atoms and with an average area of 361 times ten to the power of six km2. (361x 10**6 km2)
