Question

considere as funçoes com dominio dos numeros reais dadas por f(x)= 3x²-x+5 e g(x)=-2x+9a) calcule o valor de f(0)+ g(1)+ f(1)

Answer 1

$f(x)=3x^2-x+5$

$f(0)=3\cdot0^2-0+5=0-0+5=5$

$f(1)=3\cdot1^2-1+5=3-1+5=7$

$g(x)=-2x+9$

$g(1)=(-2)\cdot1+9=-2+9=7$

Logo

$\boxed{f(0)+g(1)+f(1)=5+7+7=19}$
