An apple costs \( \$(x+1) \). Rachel has \( \$\left(7 x^{2}+x-6\right) \). Show that she can buy a total of \( (7 x-6) \) apples if she spends all her money.

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 \( Q \).

1: \( 6 x+6 z=6 \)

\( \left. \begin{array} { l } { 14 . f ( x ) = - 2 x ^ { 2 } + 4 x + 3 } \\ { x } \\ \hline - 2 \\ { - 1 } \\ { - 1 } \\ { 0 } \\ { 1 } \\ { 2 } \end{array} \right. | \)
