Given the quadratic function f(x) = −2(x − 2)2 + 6 Homework Help ✎
Without drawing a graph, tell the coordinates of the vertex and tell if the vertex represents the maximum or minimum value of the function.
Use your graphing shortcuts to draw a graph and verify your answer to part (a).
The graphing form of a quadratic is f(x) = a(x − h) + k where the vertex is at the point (h, k).
If the vertex is the highest point on the graph, then it is a maximum.
If it is the lowest point on the graph, then it is a minimum.
