Question

please help me on how to complete the table and evaluate f(x)

x=0, x=1, x=2, x=3, x=4

f(x)7/x-1

my answers were
-7 for x=0
7/0 for x=1
7 for x=2
7/2 when divided 3.5 ?? for x=3
7/3 when divided 2.3 ?? for x=4

I am not sure if this is correct.. please HELP ME..!

Answer 1

If your expression mean :

f ( x ) = 7 / ( x - 1 )

then :


x = 0

f ( 0 ) = 7 / ( 0 - 1 ) = 7 / - 1 = - 7


x = 1

f ( 1 ) = 7 / 1 - 1 ) = 7 / 0 = infinity


x = 2

f ( 2 ) = 7 / ( 2 - 1 ) = 7 / 1 = 7


x = 3

f ( 3 ) = 7 / ( 3 - 1 ) = 7 / 2 = 3.5


x = 4

f ( 4 ) = 7 / ( 4 - 1 ) = 7 / 3 = 2.3333..
