Find the vertex of the graph of the function. f(x) = 3x^2 - 18x + 24
O (4,-2)
O (-2, 4)
O (-3,3)
O (3,-3)

It’s (3,-3)

Complete the square for 3x^2 - 18x + 24
Which will be 3(x-3)^2-3
And then set y equal to the new right side
y=3(x-3)^2-3
Use the vertex form y=a(x-h)^2
a=3
h=3
k=-3
Your answer is (3,-3)
Hope this helps:)
