Sketch the graph of the function \(f(x) = 4(x - 3)^2 - 6 \).


First, make a table of values surrounding the vertex \((3, -6)\).

     
\(x \)  \(f(x) \)
\(1\) \(f(1) = 4(1 - 3)^2 - 6 = 10\)
\(2\)
\(f(2) = 4(2 - 3)^2 - 6 = -2\)
\(3\) \(-6\)
\(4\) \(f(4) = 4(4 - 3)^2 - 6 = -2\)
\(5\) \(f(5) = 4(5 - 3)^2 - 6 = 10\)


Next, plot the points and draw a smooth curve through the points.  Label the points and the curve.
