Question

Let f(x)=12/4x+2 fine f(-1)

Answer 1

f(-1)
it's easy. instead of x we will put -1 and we will calculate the value
SO
f(-1)=12/4*(-1)+2
f(-1)=12/-4+2
f(-1)=12/-2
f(-1)=-6

Answer 2

`f(x)= (12)/(4x+2 )`


`For f(-1) =\ \textgreater \ x =\ \textgreater \ -1`


`f(-1) = (12)/(4.(-1) + 2)`


`f(-1) = (12)/((-4) + 2) = (12)/(-2) = -6`


`f(-1) = -6`
