A parabola has a vertex at (3, -2). What is the axis of symmetry? x =

-2

3

-3

2

x =3

Step-by-step explanation:

The axis of symmetry is at the vertex

The x coordinate gives the axis of symmetry

x =3

x = 3.

Step-by-step explanation:

The equation of the parabola is

f(x)  = a(x - 3)^2 - 2 where the vertex is (3, -2).

The axis of symmetry  passes though x = 3

f(2x−x2)=−3x2+6x−1

step-by-step explanation:

set up the composite function and evaluate.

f(2x−x2)=−3x2+6x−1
