The graph is cut off, so it might be hard to see/imagine, but the graph extends infinitely in both directions along the x axis

Put another way, you can plug in any x value you want into y = 10^x and you'll get some result for y. There are no restrictions to worry about (eg: 1/x where you have a division by zero error when x = 0)

@jim_thompson5910 actually thats just it.. starts at -5 and ends at 5

jim_thompson5910 · Answer

well if you were to zoom out, then the boundary would change (so we might then have xmin = -100 and xmax = 100). There is no limit to how much you can zoom out

jim_thompson5910 · Answer

it might be better to ignore the graph and focus on just y = 10^x

@jim_thompson5910 Ok (: if you need me to i can snapshot it again

jim_thompson5910 · Answer

that's ok, I don't need the pic. Hopefully you agree that you can plug in ANY number you want for x without restriction. So that's why the domain is `the set of all real numbers`
