I must be dense! I can't grasp what is apparently the most important part of algebrafunction, domain and range. Domain is x variables (input) and range is y variables (output) but what does that mean?

Best ResponseYou've already chosen the best response.0Domain is all the possible x values you can plug into the function. A lot of the time, the domain is over all real numbers, but for functions like y = 1/x, for example, there are numbers that you can't plug in for x without getting something impossible for y (in this case, the domain is all real numbers except for 0). Range is all the possible y values you can attain from a function. Again, the range is often all real numbers, but for y = 1/x, for example, the range would be, again, all real numbers except for 0, because there is no x value you could possibly plug in to make y = 0. This might help?

Best ResponseYou've already chosen the best response.0I'm going to have to reread this after some sleep. I'm shot. Thanks so much. Hopefully I can plug this into my brain.
