Question

Use the parabola tool to graph the quadratic function.

f(x)=2x^2+12x+16

Answer 1

The first thing you should know is that you need three points to be able to graph a second degree equation.
You can create a table and plot several points to obtain the parabola
In this case we will use a computational tool called wolfram alpha
Answer:
See attached image.
The graph is shown for two different intervals of the domain.
