Given:


g(x)=2x^2-4x-2

Required:

To draw the graph, and then by using the graph we have to fill the blanks.

Step-by-step explanation:

The graph of the given function is,

Vertex of g(x) is : Vertex" is a synonym for a node of a graph, i.e., one of the points on which the graph is defined and which may be connected by graph edges.

Therefore, from the above graph the vertex is

(1,-4).

The x-intercepts of g are : (-0.414.0,0) and (2.414,0)

The y-intercept is : (0,-2)

Equation of the line of symmetry of g is :


x=-(b)/(2a)

Here, a=2

b=-4

Therefore,


\begin{gathered} x=-((-4))/((2)(2)) \\ \\ x=(4)/(4) \\ \\ x=1 \end{gathered}

g has a (maximum/minimum) of: g has minimum at (1,-4).

Final Answer:

Vertex of g(x) is : (1,-4)

The x-intercepts of g are : (-0.414.0,0) and (2.414,0)

The y-intercept is : (0,-2)

Equation of the line of symmetry of g is : x=1

g has a (maximum/minimum) of: g has minimum at (1,-4).
