Please explain how you got your answer!

Domain: All real numbers or (-∞, ∞)

Range: [-9, ∞)

Step-by-step explanation:

Domain is the set of x-values that can be inputted into function f(x).

Range is the set of y-values that can be outputted by the domain.

We can see that you can plug in any x-value into the graph. Therefore, any number would work (All real numbers).

We can also see that are absolute minimum y-value is -9. Therefore, our range is from -9 (included) to infinity.

step-by-step explanation:

use that smart brain

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
