Question

What is the vertex of the function f(x)=2x2+12 x +10?
​

Answer 1

Vertex: (-3. -8)

Explanation:

Quickest and easiest way to do this is to using a graphing calc and graph the function. Once you have done so, trace the graph to the lowest point of the graph. You should be able to see that (-3, -8) is your answer.

Alternatively, you can convert this function into f(x) = a(bx - h)² + k (by Completing the Square) form to find (-h, k) as your vertex.
