I believe that there is no such function.

Explanation:

lim_(xrarr-5^-) f(x) = oo and

f'(x) <0 on (-oo,1) are not both possible.

A function can not approach infinity by decreasing.

If lim_(xrarr-5^-) f(x) = -oo, then we have a problem with concavity.

The condition f''(x) > 0 on (-oo,-3) requires f to be concave up left of x = -3.
