Question

dada a função g(x)=x2+5x+3, calcule
g(-1)
g(-5)
g(raiz quadrada de 2)
g(0)
g(2 sobre 3)
g(5)​

Answer 1

Explicação passo-a-passo:

g(-1)=(-1)²-5+3=1-5+3=-1

g(-5)=(-5)²-5.5+3=25-25+3=3

g(√2)=√2²+5√2+3=5+5√2=5(√2+1)

g(0)=0²+5.0+3=3

g(2/3)=(2/3)²+5.2/3+3=4/9+10/3+3=34/9+3=61/9

g(5)=5²+5.5+3=25+25+3=53
