Answer 1

Answer: The domain of the function for the given situation is defined by the set {0, 1, 2, 3, 4, 5, 6} and the range is defined by the set {40, 50, 60, 70, 80, 90, 100}.

Explanation:

Domain in the set of inputs and range is the set of outputs.

The function is defined as,

$T = 40 + 10 w$

Where w represents the number of wins.

Since it is given that in a chess competition players can participate in up to 6 games, therefore he can win 0 to 6 games.

So, the values of w can be 0, 1, 2, 3, 4, 5 and 6.

Find the value T for the above values of w.

For w = 0

$T = 40 + 10 (0)=40$

For w = 1

$T = 40 + 10 (1)=50$

For w = 2

$T = 40 + 10 (2)=60$

For w = 3

$T = 40 + 10 (3)=70$

For w = 4

$T = 40 + 10 (4)=80$

For w = 5

$T = 40 + 10 (5)=90$

For w = 6

$T = 40 + 10 (6)=100$

The the function can take value 40, 50, 60, 7, 80, 90 and 100.

Therefore, the domain of the function for the given situation is defined by the set {0, 1, 2, 3, 4, 5, 6} and the range is defined by the set {40, 50, 60, 70, 80, 90, 100}.
