Question

3) Dada a função f(x) = 3x2 +1, CALCULE
A) f(0)

B) f(2)

C) f(a)

D) f(2x)

E) f(2a + 1)

F) f(g)​

Answer 1

Resposta:

Explicação passo a passo:

f(x) = 3x² +1

A) f(0 ) = 3(0 )² +1=0+1= 1

B) f( 2) = 3( 2)² +1÷3.4+1=12+1=13

C) f(a ) = 3(a )² +1=3a²+1

D) f(2x) = 3( 2x)² +1=3.4x²+1=12x²+1

E) f( 2a+1) = 3( 2a+1)² +1=3.(4a²+4a+1) +1 =12a²+12a+13

F) f( g) = 3( g)² +1=3g²+1
