POR FAVOR ME AJUDEM URGENTE!!!​

Answer 1

Resposta:

g(x) = -x² + 5x + 3

a) g(-1) = -(-1)² + 5*(-1) + 3

g(-1) = -1 -5 + 3

g(-1) = -3

b) g(-5) = -(-5)² + 5*(-5) + 3

g(-5) = -25 - 25 + 3

g(-5) = -47

c) g(√2) = -(√2)² + 5*√2 + 3

g(√2) = -2  +5√2 + 3

g(√2) = 1 + 5√2

d) g(0) = -(0)² + 5*0 + 3

g(0) = 3

e) g(2/3) = -(2/3)² + 5*2/3 + 3

g(2/3) = -4/9 + 10/3 + 3

g(2/3) = 53/9

f) g(5) = -(5)² + 5*5 + 3

g(5) = -25 + 25 + 3

g(5) = 3
