Which is the graph of the function f(x) = x2 + 2x – 6? mark this and return

The graph of the function is shown below.

Step-by-step explanation:

The given function is

If an expression is defined as , then we need to add to make it perfect square.

Here, b=2 so add and subtract 1 in the above parenthesis.

        .... (1)

The vertex form of a parabola is

     .... (2)

where, (h,k) is vertex.

On comparing (1) and (2) we get

So, the vertex of the parabola is (-1,-7) and axis of symmetry is x=-1.

The x-intercepts of the equation is

Therefore, the x-intercepts are -3.646 and 1.646. The graph is shown below.

the answer is c. 23/3
