3.) which statements are true about the graph of the function f(x) = 6x – 4 + x2? check all that apply.

the vertex form of the function is f(x) = (x – 2)2 + 2.
the vertex of the function is (–3, –13).
the axis of symmetry for the function is x = 3.
the graph increases over the interval (–3, infinity symbol).
the function does not cross the x-axis.

Find the vertex of the parabola given by the formula :

1. As you can see this vertex form differ from the vertex form in option A, then A is incorrect.

2. When x=-3, f(-3)=-13 and the vertex has coordinates (-3,-13) - option B is true.

3. From the attached graph you can see that the axe of symmetry is line x=-3 that passes through the vertex. This means that choice C is incorrect.

4. From the attached graph you can see that the function is increasing for x>-3 and decreasing for x<-3. Option D is correct.

5. The graph intersects x-axis at two points (see attached diagram). Option E is incorrect.
