Restrict the Range

Write a function $restrict\_range$ that receives a function operating on floats $f$ , a lower bound $lb$ and an upper bound $ub$ . Then, $restrict\_range$ returns a new function that operates exactly as $f$ when $f(x)$ falls within the closed interval $[lb, ub]$ . Instead of outputs outside that interval, the function produced returns $float("-inf")$.
