How can you determine the domain and range of a function? [3.01, 3.02]

well, the domain is always the X, and the range is always the Y. therefore, the domain would be 3.01 and the range would be 3.02. However, if you're asked to state the domain and range in a sequence of like, numbers (example, (3,4),(-2,9),(3,6),(7,1) ) the domain would be, 3,-2,7 because domains cannot repeat. But, this example WOULDN'T be a function because x repeats. does this even make sense? sorry I'm confusing. hope this helps!

Omg Thank You @1ana27 But I Have Two More Questions <3

OpenStudy (anonymous):

sounds good!!! I'm here to help

2. What are the key features of a linear function? Explain how you find each key feature. 3.How can linear equations and functions be written and graphed? Explain how shifting the graph changes the function

honestly, i have no clue. I'm so sorry!!!! i wish i could help. I'm not so good at math but like the first question i knew. I'm so sorry!!!! maybe you could close this question though and make another one, but title it like, I WILL GIVE MEDAL bc lolz that usually catches peoples attention. so sorry i couldn't help!

2. Slope and intercept. Use two coordinate point on the graph to find slope, and then use one of these two points and slope to find intercept b by using y= mx +b
