Question

função f(x) = 3x²-5x+3 calcule :
f(2)
f(-1)
f(0)​

Answer 1

Explicação passo-a-passo:

f(2)= 3x²-5x+3

f(2)= 3.2²-5.2+3

f(2)=3.4-10+3

f(2)= 12-10+3

f(2)= 2+3

f(2)= 5

f(-1)= 3x²-5x+3

f(-1)= 3. (-1)²-5.(-1)+3

f(-1)= 3.1+5+3

f(-1)=3+5+3

f(-1)=11

f(0)= 3x²-5x+3

f(0)= 3.0²-5.0+3

f(0)= 3.0-0+3

f(0)= 0-0+ 3

f(0)=3
