2. (3 pts.) consider the relation that pairs each of your classmates full names to their birth
month. define the independent and dependent variables and determine if this relation is a
function.
independent:
dependent:
is this a function? explain your choice.

no not all of them.

step-by-step explanation:

some of them have a square base.

in simplified version   it would be x ≤-4

step-by-step explanation:

multiply each term in x ≤-4 by -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
