Question

F(x)=x²+4x-2
g(x)=-2x²+x
calcule
b)f(0)-g(1)

Answer 1

Resposta:

b)

f(0)=0²+4*0-2=-2

g(1)= -2 *1²+1 =-2+1=-1

f(0)-g(1)  = -2 -(-1)

=-2+1

= -1

Answer 2

Resposta:

b) f(0)-g(1)= -1

Explicação passo-a-passo:

f(x) x²+4x-2

f(0)=0²-4.0-2= -2

g(x)=-2x²+x

g(1)=-2.1²+1= -2+1= -1

f(0)-g(1)= -2-(-1)=-2+1=-1
