Definite Integration

Let \(\mathrm{f}(x)\) be positive for all real \(x\). If \(\mathrm{I}_1=\int_\limits{1-\mathrm{h}}^{\mathrm{h}} x \mathrm{f}(x(1-x)) \mathrm{d} x\) and \(\mathrm{I}_2=\int_\limits{1-\mathrm{h}}^{\mathrm{h}} \mathrm{f}(x(1-x)) \mathrm{d} x\), where \((2 h-1)>0\), then \(\frac{I_1}{I_2}\) is
