Question

Dado P(x) = 2x2 + 5x - 2, calcula: a) P(0) b) P(1) c) P(3)​

Answer 1

$p(x) = {2x}^{2} + 5x - 2$

---------------------------

a)

$p(0) = 2 \times {0}^{2} + 5 \times 0 - 2$

$p(0) = 2 \times 0 + 0 - 2$

$p(0) = 0 + 0 - 2$

$p(0) = - 2$

b)

$p(1) = {2 \times 1}^{2} + 5 \times 1 - 2$

$p(1) = 2 \times 1 + 5 - 2$

$p(1) = 2 + 3$

$p(1) = 5$

c)

$p(3) = 2 \times {3}^{2} + 5 \times 3 - 2$

$p(3) = 2 \times 9 + 15- 2$

$p(3) = 18+ 13$

$p(3) = 31$
