Answer 3

what did you get

Answer 4

keep in mind when you have an x-intercept of (3,0)

this means you have a rational solution (and not an irrational solution)

Answer 5

is it the last one? since its a decimal ? or the first one since it doesnt touch the x axis

Answer 6

you are correct

Answer 7

the first one is no solutions

the next two are rational

the last is irrational
