Question

Given f(x) = 6(1 − x), what is the value of f(−7)?

Answer 1

:⟶f(x)=6(1−x)

{:}\longrightarrow\tt f (-7)=6 (1-(-7)):⟶f(−7)=6(1−(−7))

{:}\longrightarrow\tt f (-7)=6 (1+7):⟶f(−7)=6(1+7)

{:}\longrightarrow\tt f (-7)=6(8):⟶f(−7)=6(8)

{:}\longrightarrow\tt f (-7)=48:⟶f(−7)=48

\therefore\sf f (-7)=48∴f(−7)=48

Answer 2

`{:}\longrightarrow\tt f (x)=6 (1-x)`

`{:}\longrightarrow\tt f (-7)=6 (1-(-7))`

`{:}\longrightarrow\tt f (-7)=6 (1+7)`

`{:}\longrightarrow\tt f (-7)=6(8)`

`{:}\longrightarrow\tt f (-7)=48`

`\therefore\sf f (-7)=48`
