A. domain: {1, 2, 3}, range: {1, 0, 1}
b. domain: {–1, 0, 1}, range: {1, 2, 3}
c. domain: {1, 0, 1}, range: {1, 2, 3}
d. domain: {1, 2, 3}, range: {–1, 0, 1}

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

step-by-step explanation:

d would equal 12
