Input x = sqrt(y) Geometric figure parabola Root y = 0 Global minimum min{sqrt(y)} = 0 at y = 0

Input x = 1/2^2 Exact result x = 1/4 Geometric figure line Alternate form x – 1/4 = 0

Input x sqrt(x) Result x^(3/2) Root x = 0 Derivative d/dx(x sqrt(x)) = (3 sqrt(x))/2 Indefinite integral integral x^(3/2) dx = (2 x^(5/2))/5 + constant Global minimum min{x sqrt(x)} = 0 at x = 0 Series representation x^(3/2) = sum_(n=0)^infinity binomial(3/2, n) (-1 + x)^n for abs(1 – x)
