$$ f(x)=x(x+3) $$

The function \(f\) is defined above. If the function \(g\) is defined by \(g(x)=f(x)-5\), what is the value of \(g(2)\)?

Summary Submit Skip Question

Since \(g(x)=f(x)-5 \) and \(f(x)=x(x+3)\),

$$ g(x)=x(x+3)-5 $$

To find \(g(2)\), simply plug in 2 where there is a \(x\).

$$ g(2)=2(2+3)-5 $$ $$ =2(5)-5 $$ $$ =10-5 $$ $$=\boxed{5 }$$
