What are the domain and range of this relation? A. domain: {22, 32, 41, 30}; range: {9, 10, 11, 12} B. domain: {9, 22, 10, 32}; range: {11, 41, 12, 30} C. domain: {9, 10, 11, 12}; range: {22, 32, 41, 30} D. domain: {11, 41, 12, 30}; range: {9, 22, 10, 32}

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;

Remove "Grade" to represent as only digits

Split to x and y values:

Where x = domain and y = range

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

the answer is 489
