#3 the answer is 4.
The reasoning for this is because x=-1 so if it is applied where x is at you have to subtract instead of multiplying in this equation. So 2xsquared is 2-1 which is 1. Same thing for 6x (6-1) which is 5. So the problem would end up being 1-5 which equals 4.

Vertex and axis of symmetry f(x)=2x^2-16x-17<br> PLEASE HELP
Law Incorporation [45]
The vertex is at (4, -49) and the axis of symmetry is at x= 4.

To find the vertex of this equation, use this method: ( \frac{-b}{2a})

a=2
b=-16

This will help get your x value and the axis of symmetry. To find the y value of the vertex, insert the x value, 4 to get your y value, -49.
