Refer Explanation section

Explanation:

Given -

f(x)=3(x-4)^2-5

It is a quadratic equation in the vertex form.

The vertex form of the quadratic [generally] is -

y=a(x-h)+k
Where (h,k) is vertex
In our equation -

h=4 [x coordinate of the vertex]
k=-5 [y coordinate of the vertex]

Vertex is (4,-5)

Take a few values on either side of x=4
Calculate corresponding y values
Tabulate it.
Graph it.

y=3x^2-24x+43
graph{3x^2-24x+43 [-10, 10, -5, 5]}

Explanation:

y=3(x-4)^2-5
y=3x^2-24x+48-5
y=3x^2-24x+43
