If, g(x)=-2(x+2)-6 what is g(b-5)=
Misha Larkins [42]

The value of g(b-5)=-2b

<u>Solution:</u>

In the notation g(x) we know that whatever is put in the parentheses is what we replace for x. In the given situation, since it is g(b-5) we have to replace every x in the function with b-5. That is if,

g(x)=-2(x+2)-6

then, g(b-5)=-2((b-5)+2)-6

\Rightarrow g(b-5)=-2(b-5+2)-6

On solving we get,

\Rightarrow g(b-5)=-2(b-3)-6\rightarrow g(b-5)=-2b+6-6

\Rightarrow g(b-5)=-2b
