Question 122598
A. for x=0
y=sqrt x+2
 = sqrt 0+2
= sqrt 2
=1.414 approx

for x = 1
y = sqrt x+2
= sqrt 1+2
=sqrt 3
= 1.732 approx

for x=2
y=sqrt x+2
= sqrt 2+2
=sqrt 4
=2

for x=3
y=sqrt x+2
=sqrt3+2
=sqrt 5
= 2.23 approx

for x=4
y=sqrt x+2
=sqrt 4+2
=sqrt 6
= 2.449 approx

B. Negative 1 and negative two can be values for x
for x= -1
y=sqrt x+2
=sqrt -1+2
=sqrt 1
=1

also x=-2
y=sqrt -2+2
=sqrt 0
=0

Values lower than -2 cannot be used because the radicand becomes negative, and will yield to imaginary number.
