Question

6) Considere a função f(x) = 3x2 + 4X -
10, determine:
a) f(-2)
b) f(-1)

c) f(0)
d) f(1)
e) f(2)​

Answer 1

$3 \times {( - 2)}^{2} + 4 \times ( - 2) - 10 \\ 3 \times 4 - 8 - 10 \\ 12 - 18 \\ - 6 \\ \\ \\ 3 \times ( { - 1)}^{2} + 4 \times ( - 1) - 10 \\ 3 \times 1 - 4 - 10 \\ 3 - 14 \\ - 11 \\ \\ \\ 3 \times 0 + 4 \times 0 - 10 \\ - 10 \\ \\ \\ 3 \times {1}^{2} + 4 \times 1 - 10 \\ 3 + 4 - 10 \\ - 3 \\ \\ \\ 3 \times {2}^{2} + 4 \times 2 - 10 \\ 3 \times 4 + 8 - 10 \\ 12 + 8 - 10 \\ 10$
