How do you graph a square root function

Question

f(x)= the square root x+1

Answer 1

y= sqr(x+1)

is upper half of

y^2 = x+1

it's a horizontal parabola, opening to the right

y=+ or - sqr(x+1) is the full parabola

y = +ssqr(x+1) is the upper half

with vertex = (-1, 0)

general formula is y = sqr(x+h)+k where (h,k) = vertex = (-1,0) for this problem
