Réponse:
a.
[tex]f( - 1) = 3 \times {( - 1)}^{2} - 2 \times ( - 1) + 4 \\ = 3 + 2 + 4 \\ = 10[/tex]
b.
[tex]f(0) = 3 \times {0}^{2} - 2 \times 0 + 4 \\ = 0 - 0 + 4 \\ = 4[/tex]
[tex]f(5) = 3 \times {5}^{2} - 2 \times 5 + 4 \\ = 75 - 10 + 4 \\ = 69[/tex]
[tex]f( \frac{1}{4} ) = 3 \times {( \frac{1}{4}) }^{2} - 2 \times \frac{1}{4} + 4 \\ = 0.19 - 0.5 + 4 \\ = 3.69[/tex]
