We have the function h(x)=(x+1)^2-3. We need to find the minimum value of h(x). To do this we fund the first derivative of h(x) and equate it to zero.

h(x) = (x+1)^2-3

h'(x) = 2(x + 1)

equating it to zero and solving for x

=> 2( x + 1) =0

=> x = -1

At x = -1, h(x) = (-1 + 1)^2 - 3 = -3.

Also h''(x) = 2 which is positive for x = -3. This means we have found the minimum value.

Therefore the minimum value of the function is -3.
