[see below]

Step-by-step explanation:

Substitute the given value into the function and then solve.

With -7:

$f(x)=6x\\\\f(-7)=6*-7\\\\\boxed{f(-7)=-42}$

With -1:

$f(x)=6x\\\\f(-1)=6*-1\\\\\boxed{f(-1)=-6}$

With 1:

$f(x)=6x\\\\f(1)=6*1\\\\\boxed{f(1)=6}$

With 7:

$f(x)=6x\\\\f(7)=6*7\\\\\boxed{f(7)=42}$
