Select the correct answer. State the domain and range of the following function.
{(6,-8), (9,3), (-3,5), (1,-6), (5,7)}

A. Domain: {-3, 1, 5, 6, 9}; Range: {-8, -6, 3, 5, 7}

B. Domain: {-3, 1, 5, 6, 3}; Range: {-8, -6, 6, 7, 9}

C. Domain: {-3, 1, 5, 6, 3}; Range: {-8, -6, 5, 7, 9}

D. Domain: {-8, -6, 3, 5, 7}; Range: {-3, 1, 5, 6, 9}​

A. Domain: {-3, 1, 5, 6, 9}; Range: {-8, -6, 3, 5, 7}

Step-by-step explanation:

Domain is x values

Range is y values

the inequality is:

250c+180g≥950

step-by-step explanation:

let c denotes the number of days in a week   miyoko worked as a cryptographer.

and g denotes the number of days in a week she works as a geologist.

now we are given that she earns $250 for every day she works as a cryptographer,and earns $180 for every day she works as a geologist.

now miyoko's goal is to earn more than $950 this week.

hence, the inequality could be represented as:

250c+180g≥950
