Question

dada a função y=x + 1,determine o valor de y para: a) x=1 b) x=-1 c)x=-2  d) x=3
                              x                                                                                   2

Answer 1

a) x=1
y = x + 1/x
y = 1 + 1/1
y = 2

b) x = -1
y = -1 + (1/-1)
y = -1 - 1
y = -2

c) x = -2
y = -2 + 1/-2
y = -2,5

d) x = 3/2 = 1,5
y = 1,5 + 1/1,5
y = 1,5 + 0,66
y = 2,16
esse fiquei em dúvida D:
