Question

Use the parabola tool to graph the quadratic function. f(x)=2x^2 +12x+16 Graph the parabola by first plotting its vertex and then plotting a second point on the parabola.

Answer 1

(-3, -2) is the vertex. 

You can find this by plugging into -b/2a to find the x value and using the x value to find the y value. 

And another spot on the vertex would be (0, 16), which is the y intercept.
