Question

When will the dependent variable in the equation Y=[(sqrt)(x+4-3)] equal or exceed 4?
• x ≥ –0.17
• x ≥ 45
• x ≥ 48
• x ≥ 53
Show how.

Answer 1

I suppose you mean
Y(x)=sqrt(x+4)-3

in which case you can evaluate the function for the various given values and see which one, if any, gives Y(x)=0.

Answer 2

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

Answer 3

Not sure what your choice is, and also if the actual question should read:
Y(x)=sqrt(x+4)-3
or
Y(x)=sqrt(x+4-3) [as you had it]
Can you check if there is a typo?
