1-1 Relations and Functions The following list details the numbers of tickets sold for a talent show: grade 9: 22; grade 10: 32;

zlopas [31]

Answer:

$Domain = \{9, 10, 11, 12\}$

$Range = \{22, 32, 41, 30\}$

Step-by-step explanation:

Given

Grade 9: 22

Grade 10: 32

Grade 11: 41

Grade 12: 30

Required

Determine the domain and the range

The domain and range of a function is represented as thus (x,y)

From the given parameters;

$(x,y) = (Grade\ 9, 22), (Grade\ 10, 32) (Grade\ 11, 41), (Grade\ 12, 30)$

Remove "Grade" to represent as only digits

$(x,y) = (9, 22), (10, 32), (11, 41), (12, 30)$

Split to x and y values:

Where x = domain and y = range

$Domain = \{9, 10, 11, 12\}$

$Range = \{22, 32, 41, 30\}$

So, from the list of given options; option C answers the question.

Determine g(x+a)−g(x) for the following function. g(x)=4x2−6x

Ilia_Sergeevich [38]

Answer:

8ax + (4a²- 6a)

Step-by-step explanation:

g(x)=4x²−6x

g(x+a)

= 4(x+a)² - 6(x+a)

= 4( x² + 2ax + a²) - 6x - 6a

= 4x² + (4)2ax + (4)a² - 6x - 6a

= 4x² + 8ax + 4a² - 6x - 6a

= 4x² + 8ax - 6x + 4a²- 6a

= 4x² + (8a - 6)x + (4a²- 6a)

g(x+a) - g(x)

= [4x² + (8a - 6)x + (4a²- 6a)] - (4x²−6x)

= 4x² + (8a - 6)x + (4a²- 6a) - 4x² + 6x

= (8a - 6)x + (4a²- 6a) + 6x

= (8a - 6 + 6)x + (4a²- 6a)

= 8ax + (4a²- 6a)
