Question

if f(x) = 0.5 (1-x), what is the value of f(-1)?
PLEASE HELP

Answer 1

it is simple, we have to set \(x=-1\), so we can write this:
\[f\left( 1 \right){\text{ }} = {\text{ }}0.5{\text{ }}\left( {1 - \left( { - 1} \right)} \right) = ...?\]

Answer 2

oops...
\[f\left( { - 1} \right){\text{ }} = {\text{ }}0.5{\text{ }}\left( {1 - \left( { - 1} \right)} \right) = ...?\]

Answer 3
