Question 949254: Consider the following function
f(x)=-4x^2-8x-3
a. Describe the transformation we would apply to the basic function g(x)=x^2, to obtain f.
b. Give the vertex and axis of symmetry.

My answer after graphing it.
a. The graph of a f(x)=-4x^2-8x-3 is a reflection in the x axis, a horizontal shift of 1 unit to the left, and a vertical shift of 1 unit upward of the graph of g(x)=x^2
The graph of a f(x)=-4x^2-8x-3 is a vertical stretch of the graph of g(x)=x^2 by a factor of 4.
b. The vertex is (-1,1) and the axis of symmetry is -1.
This doesn't look right and asking for assistance. Thanks.
