indentify the vertex and axis of symmetry of each. then sketch the graph-the instructions f(x)=-3(x-3) squareed -4

we have the equation

f(x)=-3(x-3)^2-4

the equation of a vertical parabola in vertex form is equal to

y=a(x-h)^2+k

where

(h,k) is the vertex

The given equation is written in vertex form

so

the vertex is the point (3,-4)

The axis of symmetry in a vertical parabola is equal to the x-coordinate of the vertex

so

axis of symmetry is

x=3

using a graphing tool

see the attached figute

the given equation is

f(x)=-3(x-3)^2-4

the equation in vertex form is

y=a(x-h)^2+k

(h,k) is the vertex

that means

(h,k)=(3,-4)
