Answer:

The function of the quadratic equation in vertex form is given below as


f(x)=7(x_{}+1)^2-9

From the graph of the function above, we can see that the leading coefficient is greater than zero ,

Hence,

The graph opens up

Part B:

To figure out the vertex of the graph, we will use the general form of a quadratic function given below as


f(x)=a(x-h)^2+k

By comparing coefficients, we will have


\begin{gathered} f(x)=a(x-h)^2+k \\ f(x)=7(x+1)^2-9 \\ a=7,h=-1,k=-9 \end{gathered}

The coordinates of the vertex is represented below as


(h,k)\Rightarrow(-1,-9)

Hence,

The vertex of the graph in ordered pair is = ( -1. -9)
