Use the parabola tool to graph the quadratic function. f(x)=2x2+4x−16

Refer the attached figure.

Step-by-step explanation:

Given : Quadratic function

To find : The graph of the quadratic function using parabola tool?

Solution :

The given function

First we find the vertex form of the equation

Where, a=2 ,b=4 , c=-16

Vertex is

So, The vertex of the equation is (-1,-18)

Now, we find y- intercept by putting x=0 in the equation

y- intercept (0,-16)

Now, we find x- intercept by putting y=0 in the equation

x- intercepts are (-4,0) and (2,0)

Placing all the points and plot a graph.

Refer the attached figure below.
