Charla wants to determine the vertex of the function f(x) = x2 – 18x + 60 by changing the function into vertex form. Which state
ment about the vertex of the function is true? The x-coordinate of the vertex is greater than the y-coordinate. The x-coordinate of the vertex is negative. The y-coordinate of the vertex is greater than the y-intercept. The y-coordinate of the vertex is positive.
