Answer:


h(x)=-8(x+7)^3+2

Step-by-step explanation:

Given the function:


f\mleft(x\mright)=-4x^3+1

Stretching f(x) vertically by a factor of 2 gives:


2f(x)=2(-4x^3+1)

Next, shifting it by 7 units left:


\begin{gathered} 2f(x+7)=2(-4(x+7)^3+1) \\ h(x)=-8(x+7)^3+2 \end{gathered}

The second option is correct.
