Question

F(x) = x2+1/x qual o valor de f(2)+ f(1/2)

Answer 1

f(2) = 2.2 + 1/2
f(2) = 4 + 1/2
f(2) = 9/2

f(1/2) = 1/2.2 + 1/1/2
f(1/2) = 1 + 2
f(1/2) = 3

f(2) + f(1/2) =

9/2 + 3 =

15/2

Answer 2

f(x) = x² +1/x

f(2) = 2² + 1/2

f(2) = 4 + 1/2

f(2) = 9/2

f(1/2) = (1/2)² + 1/(1/2)

f(1/2) = 1/4 + (1*2/1)

f(1/2) = 1/4 + 2

f(1/2) = 9/4

f(2) + f(1/2) = 9/2 + 9/4

f(2) + f(1/2) = 27/4
