Question

Sendo a função F:R* -> R que tal F (X) = 1+x2, calcule:
x

a) F (2)
b) F (-2)
c) F (1/4)
d) F (-1/4)

Answer 1

 F (X) = 1+x2, calcule:x

a) F (2) = 1 +(1)² ==> 1+1==> 2
b) F (-2) = 1 +(-2)² ==> 1+4==> 5
c) F (1/4) = 1 +(1/4)² ==> 1+1/16==> (16+1)/16==> 17/16
d) F (-1/4) = 1 +(-1/4)² ==> 1+1/16==> (16+1)/16==> 17/16
