Question

SI F(x)=x2 + 5. Halla:
f(-5)+ f(1) f(3)​

Answer 1

Respuesta:

22

Explicación paso a paso:

Halla:  f(-5) + f(1) f(3)​

F(x) = x.2 + 5

Reemplazas:

f(-5) = -5(2) + 5

f(-5) = -10 + 5

f(-5) = -5

f(1) = 1(2) + 5

f(1) = 2 + 5

f(1) = 7

f(3) = 3(2) + 5

f(3) = 6 + 5

f(3) = 11

Piden:

f(-5) + f(1) f(3)​

-5 + 7 . 11

2 . 11
