the domain is all the x-values in which the function exists
look at your x-axis and scroll up and down with your eyes for each value on the x-axis
and if you see a part of the curve (line or whatever) there then the function exist and so that number is apart of the domain
for example does your function exist at x=-2?|dw:1440973842510:dw|
we see the curve does exist at x=-2
so x=-2 is apart of the domain
so what do you think the whole domain is for your parabola here?
So would the answer be all real numbers? I was stuck between B and C, but with what you said, I'm leaning towards C.
yes all real numbers the curve exists for all x-values
c is the domain while d is the range
Thank you so much! My textbook has like one page dedicated to domain/range, but it doesn't really tell you how to calculate what the domain is. I really appreciate the help!
