Question

I need help I suck at math please help me

Answer 1

It is given that

`\begin{gathered} g(x)=3(2^{x)\text{ }}and\text{ h}(x)=2^(x-1) \\ \text{And we n}ed\text{ to find k(x)=(g-h)(x)} \end{gathered}`

Now

`\begin{gathered} k(x)=(g-h)(x) \\ =g(x)-h(x) \\ =3(2^x)-(2^{x-1)^{}} \\ =2^x(3-(1)/(2)) \\ =2^x((6-1)/(2)) \\ =2^x((5)/(2)) \\ =5(2^(x-1)) \end{gathered}`

So the correct option is

`5(2^(x-1))`
