Question

dado o polinomio p(x) =2x+5 encontre o valor numerico de

Answer 1

Bom dia! Tudo bem?

a) p(x) =2x+5 >> p(1) =2*1+5 >> p(1) =2+5 >> p(1) = 7

b) p(5) =2x+5 >> p(5) =2*5+5 >> p(5) =10+5 >> p(5) = 15

c) p(x) =2x+5 >> p(0) =2*0+5 >> p(0) =0+5 >> p(0) = 5

d) p(-1) =2x+5 >> p(-1) =2*(-1)+5 >> p(0) =-2+5 >> p(x) = 3

e) p(-5) =2x+5 >> p(-5) =2*(-5)+5 >> p(-5) =-10+5 >> p(-5) =-5

Answer 2

Olá,

a) p(1) = 2.1 + 5 = 2 + 5 = 7

b) p(5) = 2.5 + 5 = 10 + 5 = 15

c) p(0) = 2.0 + 5 = 0 + 5 = 5

d) p(-1) = 2.(-1) + 5 = -2 + 5 = 3

e) p(-5) = 2.(-5) + 5 = -10 + 5 = -5

Espero ter ajudado!!!
