Resposta:

[tex]p ^{ - 1} (x) = \frac{1}{3} x - 11 \\ [/tex]

Explicação passo-a-passo:

[tex]p(x) = 6x \times 4 + 3 \times 3 - 2x + x \times 5 \\ y = 6 \times 4 + 3 - 2x + x \times 5 \\ x = 6 \times 4 + 3 \times 3 - 2y + y \times 5 \\ 6 \times 4 + 3 \times 3 - 2y + y \times 5 = x \\ 24 + 9 - 2y + 5y = x \\ 33 + 3y = x \\ 3y = x - 33 \\ y = \frac{1}{3} x - 11 \\ \\ p^{ - 1} (x) = \frac{1}{3} x - 11[/tex]
