Using the concepts of domain and range, it is found that:
- The domain of the relation is {-1, 2, 3, 4}.
- The range of the relation is {-1, 0, 2, 4}.
<h3>What are the domain and range of a relation?</h3>
- The domain of a function is the set that contains all possible input values. On a graph, it is given by the values of x.
- The range of a function is the set that contains all possible output values. On a graph, it is given by the values of y.
In this graph, the points represented are given by: {-1, 2}, {2,0}, {3,-1} and {4,4}. Hence:
- The domain of the relation is {-1, 2, 3, 4}.
- The range of the relation is {-1, 0, 2, 4}.

Mr. Leonard gets £ 45.84375 as discount
<em><u>Solution:</u></em>
The oil tank can take up to 1200 liters of oil
There are already 450 liters of oil in the tank
The remaining oil which is to be added is given by :
Remaining oil = 1200 - 450 = 750 liters
The price of oil is 81.5 p per liter
<em><u>Then calculate the total price of 750 L of oil:</u></em>
Thus total price is 61125 p
Mr Leonard gets a 7.5% discount on the price of the oil
Therefore,
Discount amount = 7.5 % of 61125
Thus he gets 4584.375 p
We convert p to £
1 p = 0.01£
4584.375 x 0.01 = £ 45.84375
Thus he gets £ 45.84375 as discount

Answer:
(a, b, c) = (30°, 60°, 105°)
Step-by-step explanation:
Angle "a" and 30° are vertical angles, hence equal.
Angle "b" and angle "a" are complementary angles, so b = 90° -30° = 60°.
Angle "c" is supplementary to the one marked 75°, so is 180° -75° = 105°.
___
Angles "a" and "b" are complementary because the sum of angles in a triangle is 180° and the third angle in that triangle is 90°. Then ...
a+b = 180°-90° = 90°
___
75° and "c" are supplementary, because they are linear angles. The angle measure of a line is 180°, so that is their total measure.
