The function appears to be a piecewise function, combining multiple operations in different intervals of the input domain. There are different behaviors for negative and positive inputs. For negative values, the function approaches zero as the input decreases, and fluctuates for values close to zero. For positive values, the function appears to behave more linearly, starting at 7.5 for an input of 1 and decreasing as the input increases to a value approaching -2.
