5. Rajah di bawah menunjukkan suatu graf fungsi kuadratik yang menyilang paksi-x pada titik \( P \) dan titik \( Q \). Tentukan koordinat bagi titik \( P \) dan titik \( Q \).

Two cubic roots are given below. \( \sqrt[3]{27} \) and \( \sqrt[3]{343} \) Write \( \mathrm{a} \times \mathrm{a} \times \mathrm{a} \times \mathrm{a} \times \mathrm{a} \times \mathrm{a} \) in the form of indices (b) Multiply the given two cubic roots. c) Prove that: \( \left(\frac{\mathrm{x}^{a}}{\mathrm{x}^{b}}\right)^{a+b}\left(\frac{x^{b}}{x^{c}}\right)^{b+c}\left(\frac{\mathrm{x}^{c}}{\mathrm{x}^{a}}\right)^{c+a}=1 \)

a) \( f(x)=|x+4|+2 \) b) \( f(x)=- \) c) \( f(x)=3 x^{2}-x-2 \)
