2nd posting - my mistake

When will the dependent variable in the equation y= sqrt [x+4-3] equal or exceed 4
• x ≥ –0.17
• x ≥ 45 ** is it this one?
• x ≥ 48
• x ≥ 53

2 answers

why not just say "x+1" instead of "x+4-3"?

And if x>=45 works, why not x>=48? or x>=53?

I still suspect a typo.
I may not be writing it correctly but I did find out it was x =45.
Thanks for you help.
